I am working on creating nodes and relationships. For a particular type of node, there is a hyperlink that I would like attach to it(perhaps as a property) so that users would be able to click and see more details on that node.
Does anyone know if that is possible? Happy to provide more details if needed.
Thanks in advance.
A standard string property would work just fine. It works as a regular hyperlink in the Neo4j browser.
CREATE (n:Sample {link: "https://google.com"}) RETURN n;

In a given area path, I would to get the list of stories that does not have parent feature link. How should I write the query for it?
To achieve you could change the type of your query to the Work items and Direct Links query, then choose the option to pull back all work items without any matching links. The results will still be a flat list.
In the filters for top level work items, just add a filed to specify a detail area path and choose corresponding work item type.
More details please take a look at our official here: Use direct links to view dependencies
Hope this helps.
I am using node.js to connect to the neo4j database. Whenever I have to set an index for a node, I do it manually by going to the neo4j browser (localhost:7474).
CREATE INDEX ON :user(username)
First of all to be clear, this is an automatic index? Any changes or additions to :user are automatically maintained? Let me know if I am wrong.
If so, how does full text index work on neo4j? Is it the same process and neo manages automatically? For example does the following create full text index? Or we need to do something else?
CREATE INDEX ON :user(aboutme)
I built my own nodejs adapter to connect to neo4j, and so I only have access to cypher queries at the moment. To create an index I only have access to cypher or the browser (7474). So what is the proper way to create automatic fulltext index, preferably from the browser itself? And how do I access it using the cypher (or do I have to access it? does neo automatically figure out what index to use?). Online documentation and tutorials are a bit complicated for beginners :/ .
(I want to be able to do text search on the :user(aboutme) property)
If you want a full text index (where you can use the index to match on parts of the string and not the full, exact string), that isn't currently supported by the new cypher automatic indexes (like CREATE INDEX ON :user(username)). To do that you need to use what are called the legacy indexes. These use lucene under the covers and are much more powerful, but I believe they will eventually go away once that same functionality is supported with the new indexes.
Personally for full-text search I prefer using something like elasticsearch as it is easier to set up and use.
Using a default index, one can do nodeIndex.get("message", "Hello") for exact matches, or nodeIndex.query("message", "Hel*") for approximate Lucene-based queries. This works correctly for me from Java.
But how do I do approximate queries through the webadmin Data Browser interface? Exact matches work fine, such as:
node:index:nodeIndex:message:"Hello"
but I can't see how to do the wildcard queries. The syntax is shown in the pop-up help panel as:
node:index:[index]:[query]
but I don't know what to put for the [query] part, and can't find any examples of this in the manual or the wiki. Have tried the following without success:
node:index:nodeIndex:"message:Hel*"
node:index:nodeIndex:message:"Hel*"
node:index:nodeIndex:"Hel*"
node:index:nodeIndex:Hel*
This should work:
node:index:nodeIndex:message:Hel*
The queryis message:Hel* so you just append it, more complex queries are also possible.
See the lucene syntax guide.
node:index:nodeIndex:message:Hel* OR message:Wor*
Issue created. https://github.com/neo4j/community/issues/138
I get the tree in symfony with propel with this way:
$tree = FoldersQuery::create()->findTree();
Now, how to list the tree with each child properly?
I want parents be on a specific div, children on an another div and list them. But how?
How to get the relationships between each item and know how to render it?
Thanks a lot.
You should read this documentation http://www.propelorm.org/behaviors/nested-set.
You can get all children with getChildren(), know whether it's a root node or not with isRoot(), know the level, ...
See more on the API section, it will help you :)
I need a delphi component for Delphi 2007 win32 that have features like Google search text box.
** While User writing search key it should fill/refresh the list with values, and user can select one of them.
**User can go up and down list and can select one of them.
**List should contain codes and text pair, so user can select text and I can get code for database operations.
(Google can highlight the search text in List but I think it is not possible with Delphi 2007, so it is not expected.)
I tried Dev Express TcxMRUEdit, however it doesn't meet my needs
Since you have DevExpress, why don't you try the cxLookupComboBox in lsEditMode and with ImmediateDropDown = True?
Check out woll2woll components. The TLookupcombobox has done this since Delphi 3 (or earlier). This is not spam, I just use the library.

I also had the same problem and unfortunately didn't find a suitable component. I was also inspired from google.
So it turned out to be easier for me to "simulate a component" by using an editbox and a grid placed under it. As the user types something in the editbox the query refreshes and the proper resulst are shown in the grid. I have many columns in the grid, the query results try to match all the fields (so if I type 'po', the query will return all records where any field is like 'po%'). I also added a delay of 500ms after the user types to avoid to run too many unnecessary queries (another aproach could be to kill the thread as the user strikes a new key, if the query is run in a thread).
In this way I obtained the required functionality, even if without higlighting the search text, anyway my users are delighted by this.
In every place I am using this "component" I am attaching a query at runtime so it can be used in many different forms.
I somehow was also inspired by the skype UI: when you display the lsit of contacts you can type something and the contacts will be filtered accordingly (skype uses an editbox + grid/listbox).
