I am using stardog as semantic database.
Query: except all kinds of Mango & vegetable.
Expected output: except all kind of Mangoes & vegetables.
Actual output: 0 results.
I have tried English Analyzer library for stemming. But as per my understanding, it works only when we search with free-text (i.e. tag:stardog:api:property:textMatch).
If I enable free-text, I don't mind results like 'except all kinds of vegetable'. But as free-text matches all words and combinations, many results are irrelevent (eg. except trips).
Current query:
select * where {
?s a p:NamedEntity .
?s hasTitle ?l.
(?l ?score) <tag:stardog:api:property:textMatch>
'except all **kinds** of **Mango** & **vegetable**'
}order by desc(?score)
My Question:
Can English analyzer be used without free-text search?
Is there any other way to achieve the same?
You can specify custom analyzers.

I was trying to write a simple FluxQL Query in Grafana Dashboard that uses a variable
m1(of type constant)(which contains the name of the measurement)
I created the variable m1 in grafana dashboard variables
m1 = my-measurement
and tried to run the following queries but non of them worked and they either say expression request error or No Data)
i.e
SELECT count("fails") FROM "/^${m1:raw}$/"
SELECT count("fails") FROM "/^${m1}$/"
SELECT count("fails") FROM $m1" (expression request error)
SELECT count("fails") FROM "$m1"
SELECT count("fails") FROM "${m1}"
The only query worked was without dashboard variables
SELECT count("fails") FROM "my-measurement"
How can I use the variables to work for that query.
On the similar ground I tried to make a custom variable(myVar) for which we take integer input values from user and on that basis where clause should work, but same error occurs either no data or expression request error
What I tried was
SELECT count(*) from "my-measurement-2" WHERE ("value" > $myVar)
How should I solve these issues?Please help
You may have a problem with
1.) syntax
SELECT count("fails")
FROM "${m1:raw}"
2.) data
You may correct query syntax, but query can be very inefficient. Query execution may need a lot of time - so it's better to have timefilter, which will use selected dashboard time range (make sure you have some data in that time range)
SELECT count("fails")
FROM "${m1:raw}"
WHERE $timeFilter
3.) Grafana panel configuration
Make sure you are using suitable panel - for query above Stat panel is a good option (that query returns only single value, not timeseries, so time series panel types may have a problem with that).
Generally, use query inspector to see how are variables interpolated - there can be "magic", which is not obvious - e.g. quotes which are added around numeric variables, so then it is string filtering and not numeric filtering on the InfluxDB level.
I want to find all usages of my react component in code.
I tried <Button> but Special chars <> are not supported.
Tried "Button" and i get "Button" and button with lowercase as results as well.
So exact match is also not supported.
Is there is a way to find a string exactly without any additional results?
Unfortunately, search symbols (<> and "" in your scenario) is not supported in code search.
In tfs the symbol "" is used for finding an exact match to a set of words by enclosing your search terms in double-quotes. For example, "Client not found".
Is there is a way to find a string exactly without any additional
results?
Yes, but it seems a little complex, just reference my answer in another thread:Is there a way to make TFS code search recognize the "#" symbol?
Checked for some characters in code search. You can't use the symbol
characters except * and ? as part of your search query, which
including below characters: . , : ; / \ ` ' " # = ! # $ & + ^ | ~ < >
( ) { } [ ]. The search will simply ignore these symbols.
But you can use wildcard characters * and ? to broaden your search.
You can use wildcard characters anywhere in your search string except
as a prefix in a simple search string or a query that uses a code type
filter. For example, you cannot use a search query such as
*RequestHandler or class:?RequestHandler. However, you can use prefix wildcards with the other search filter functions; for
example, the
search query strings file:*RequestHandler.cs and repo:?Handlers are
valid.
Please see Broaden your search with wildcards for details.
If you want to search the strings including these symbol exactly(such
as '#' here), you can code search with other strings (eg,
testexample.com here) to narrow down the scope first, then copy the
specific code to text editor which support the symbols (eg,
Notepad++), then search stings with the symbol characters.
Besides, if you are using Git, another workaround is using the code
search tool Hound: a lightning fast code search tool, it supports
the symbol characters. Reference this thread to use it:
How can I publish source code (Visual Studio) on a intranet?
Also, there is a User Voice here to suggest the feature, you can go and vote it up to achieve that in future.
I can query using Cypher in Neo4j from the Panama database the countries of three types of identity holders (I define that term) namely Entities (companies), officers (shareholders) and Intermediaries (middle companies) as three attributes/columns. Each column has single or double entries separated by colon (eg: British Virgin Islands;Russia). We want to concatenate the countries in these columns into a unique set of countries and hence obtain the count of the number of countries as new attribute.
For this, I tried the following code from my understanding of Cypher:
MATCH (BEZ2:Officer)-[:SHAREHOLDER_OF]->(BEZ1:Entity),(BEZ3:Intermediary)-[:INTERMEDIARY_OF]->(BEZ1:Entity)
WHERE BEZ1.address CONTAINS "Belize" AND
NOT ((BEZ1.countries="Belize" AND BEZ2.countries="Belize" AND BEZ3.countries="Belize") OR
(BEZ1.status IN ["Inactivated", "Dissolved shelf company", "Dissolved", "Discontinued", "Struck / Defunct / Deregistered", "Dead"]))
SET BEZ4.countries= (BEZ1.countries+","+BEZ2.countries+","+BEZ3.countries)
RETURN BEZ3.countries AS IntermediaryCountries, BEZ3.name AS
Intermediaryname, BEZ2.countries AS OfficerCountries , BEZ2.name AS
Officername, BEZ1.countries as EntityCountries, BEZ1.name AS Companyname,
BEZ1.address AS CompanyAddress,DISTINCT count(BEZ4.countries) AS NoofConnections
The relevant part is the SET statement in the 7th line and the DISTINCT count in the last line. The code shows error which makes no sense to me: Invalid input 'u': expected 'n/N'. I guess it means to use COLLECT probably but we tried that as well and it shows the error vice-versa'd between 'u' and 'n'. Please help us obtain the output that we want, it makes our job hell lot easy. Thanks in advance!
EDIT: Considering I didn't define variable as suggested by #Cybersam, I tried the command CREATE as following but it shows the error "Invalid input 'R':" for the command RETURN. This is unfathomable for me. Help really needed, thank you.
CODE 2:
MATCH (BEZ2:Officer)-[:SHAREHOLDER_OF]->(BEZ1:Entity),(BEZ3:Intermediary)-
[:INTERMEDIARY_OF]->(BEZ1:Entity)
WHERE BEZ1.address CONTAINS "Belize" AND
NOT ((BEZ1.countries="Belize" AND BEZ2.countries="Belize" AND
BEZ3.countries="Belize") OR
(BEZ1.status IN ["Inactivated", "Dissolved shelf company", "Dissolved",
"Discontinued", "Struck / Defunct / Deregistered", "Dead"]))
CREATE (p:Connections{countries:
split((BEZ1.countries+";"+BEZ2.countries+";"+BEZ3.countries),";")
RETURN BEZ3.countries AS IntermediaryCountries, BEZ3.name AS
Intermediaryname, BEZ2.countries AS OfficerCountries , BEZ2.name AS
Officername, BEZ1.countries as EntityCountries, BEZ1.name AS Companyname,
BEZ1.address AS CompanyAddress, AS TOTAL, collect (DISTINCT
COUNT(p.countries)) AS NumberofConnections
Lines 8 and 9 are the ones new and to be in examination.
First Query
You never defined the identifier BEZ4, so you cannot set a property on it.
Second Query (which should have been posted in a separate question):
You have several typos and a syntax error.
This query should not get an error (but you will have to determine if it does what you want):
MATCH (BEZ2:Officer)-[:SHAREHOLDER_OF]->(BEZ1:Entity),(BEZ3:Intermediary)- [:INTERMEDIARY_OF]->(BEZ1:Entity)
WHERE BEZ1.address CONTAINS "Belize" AND NOT ((BEZ1.countries="Belize" AND BEZ2.countries="Belize" AND BEZ3.countries="Belize") OR (BEZ1.status IN ["Inactivated", "Dissolved shelf company", "Dissolved", "Discontinued", "Struck / Defunct / Deregistered", "Dead"]))
CREATE (p:Connections {countries: split((BEZ1.countries+";"+BEZ2.countries+";"+BEZ3.countries), ";")})
RETURN BEZ3.countries AS IntermediaryCountries,
BEZ3.name AS Intermediaryname,
BEZ2.countries AS OfficerCountries ,
BEZ2.name AS Officername,
BEZ1.countries as EntityCountries,
BEZ1.name AS Companyname,
BEZ1.address AS CompanyAddress,
SIZE(p.countries) AS NumberofConnections;
Problems with the original:
The CREATE clause was missing a closing } and also a closing ).
The RETURN clause had a dangling AS TOTAL term.
collect (DISTINCT COUNT(p.countries)) was attempting to perform nested aggregation, which is not supported. In any case, even if it had worked, it probably would not have returned what you wanted. I suspect that you actually wanted the size of the p.countries collection, so that is what I used in my query.
Inside my model at searchable block I have index time added_at.
At search block for searching I added with(:added_at, nil), made reindex and now inside search object I have:
<Sunspot::Search:{:fq=>["-added_at_d:[* TO *]"]...}>
What is the meaning of this [* TO *] ? Something went wrong?
By adding with(:added_at, nil) you narrow down the search results to documents having no values in the field added_at, so we can expect the corresponding query filter to be defined as :
fq=>["added_at_d:null"] # not valid
The problem is that Solr Standard Query Parser does not support searching a field for empty/null value. In this situation the filter needs to be negated (exluding documents having any value in the field) so that the query remains valid.
The operator - can be used to exclude the field, and the wildcard character * can be used to match any value, now we can expect the query filter to look like :
fq=>["-added_at_d:*"]
However, although the above is valid for the query parser, using a range query should be preferred to prevent inconsitent behaviors when using wildcard within negative subqueries.
Range Queries allow one to match documents whose field(s) values are
between the lower and upper bound specified by the Range Query. Range
Queries can be inclusive or exclusive of the upper and lower bounds.
A * may be used for either or both endpoints to specify an open-ended range query.
Eventually there is nothing wrong with this filter that ends up looking like :
fq=>["-added_at_d:[* TO *]"]
cf. Lucene Range Queries, Solr Standard Query Parser
Symptoms:
Searching for a single word (i.e. "Snap") works
Searching for another word contained in the same field (i.e. "On") also works
Searching for "Snap On" at the same time returns 0 results, even though it shouldn't.
The setup:
SQL Server 2008 R2 with Advanced Features
nopCommerce 3.0
Things I have done:
I added the Product.MetaKeywords column to the full text search catalog
I added a bit into the Stored Procedure that performs the search to search through the MetaKeywords
Now the nopCommerce boards are fairly slow, but I'm positive the problem is within the SQL Stored Procedure anyway, so I figured I would ask for some SQL Server help here, even if you aren't familiar with the nopCommerce web app, you may have some information you can help me with.
The stored procedure in question is too large to post entirely here, but basically it dynamically adds "OR" or "AND" in between the keyword searches to generate the phrase used in a Contains clause. It selects through several unions various searchable fields by using Contains.
Here is the bit I added into the stored procedure
SET #sql = #sql + '
UNION
SELECT p.Id
FROM Product p with (NOLOCK)
WHERE '
IF #UseFullTextSearch = 1
SET #sql = #sql + 'CONTAINS(p.[MetaKeywords], #Keywords) '
ELSE
SET #sql = #sql + 'PATINDEX(#Keywords, p.[MetaKeywords]) > 0 '
#Keywords, at this point, if I am reading the procedure correctly, has a value of: "Snap* AND On*"
I don't understand why my query of "Snap On" returns 0 results, but "Snap" and "On" individually work fine.
The minimum search length is set to 1, so it's not that.
I should add that searching for "Snap* OR On*" works, but I cannot use OR because then searching for "Snap On" will also return "Snap Dragon" and other unrelated things.
--EDIT--
The problem wasn't any of that. I got some advice elsewhere and the problem was actually the stoplist. I managed to fix my issue simply by changing the stoplist on the product table from <system> to <off>.
To do this, follow these steps.
browse to your table in SQL Server management studio
Right click on the table and select "Full-Text Index"
Select "Properties" under "Full-Text Index"
In the "General" Tab, change "Full-Text Index Stoplist" to <off>
I had to do it this way because I was unable to get the transact SQL to work. It kept telling me there was no such object as the table I was attempting to modify. If anyone can provide any insight on how the Alter fulltext index statement works, I'm interested, because I was following the example on the MSDN page to the T and it just kept telling me there was no such object named Product.
The asterisk is not a plain old wildcard. If you are using it anywhere other than at the end of a search term, you're probably not using it correctly. See answers to a similar question
SQL Contains Question
In your case, each search term must be quoted separately. See this example from the docs http://technet.microsoft.com/en-us/library/ms187787(v=sql.90).aspx
SELECT Name
FROM Production.Product
WHERE CONTAINS(Name, '"chain*" OR "full*"');
