I want to know can we index json into solr and if yes can we search the document on basis of key or value of json.
For eg:
Can we index
[
{
"id": "chapter1",
"title" : "Indexing Child Documents in JSON",
"content_type": "chapter",
"_childDocuments_": [
{
"id": "1-1",
"content_type": "page",
"text": "ho hum... this is page 1 of chapter 1"
},
{
"id": "1-2",
"content_type": "page",
"text": "more text... this is page 2 of chapter 1"
}
]
}
]
I have indexed custom Jsons and the answer to your question is 'Yes', We can index Json into Solr using Admin UI or CLI.
We can do Search query in solr, and search is performed on 'values'.

My goal is to use an input array of strings (fake emails) as a search query for documents in my MongoDB database, which I am powering using TypeORM. This way if I want to search for documents using more than one email at a time, I can do that. Meaning I want to be able to feed in:
query = ["kim#gmail.com", "jim#gmail.com", "sarah#gmail.com"] and get 3 different documents where document one has kim#gmail.com as the attendee, jim#gmail.com is another document's attendee field, and sarah#gmail.com is the third document's attendee (or is among them).
I want to use an email as a query to search for and return all documents where the array field has the email in the array.
So as an example here is the results for the "get all documents" endpoint right now:
[
{
"_id": "6283d7ad706445dc33319bcb",
"hostUsername": "jack",
"hostEmail": "jack#outlook.com",
"meetingName": "nervous-fish-hautily-vetting",
"startTime": "2022-12-12T08:00:00.000Z",
"attendees": [
"kate#gmail.com",
"sawyer#gmail.com"
]
},
{
"_id": "6284235e662f7dfb073e2cbc",
"hostUsername": "jacob",
"hostEmail": "jacob#gmail.com",
"meetingName": "eager-fish-hautily-vetting",
"startTime": "2022-12-12T08:00:00.000Z",
"attendees": [
"kate#gmail.com",
"benjaminlinus#gmail.com"
]
},
{
"_id": "6283d7c3706445dc33319bcc",
"hostUsername": "richard",
"hostEmail": "richard#outlook.com",
"meetingName": "eager-cat-hautily-subtracting",
"startTime": "2022-12-12T08:00:00.000Z",
"attendees": [
"johnlocke#gmail.com",
"hurley#gmail.com"
]
},
{
"_id": "6283d82b706445dc33319bcd",
"hostUsername": null,
"hostEmail": "richard#outlook.com",
"meetingName": "nervous-cat-hautily-jumping",
"startTime": "1970-01-01T00:00:00.000Z",
"attendees": null
},
{
"_id": "6283d8af706445dc33319bce",
"hostUsername": null,
"hostEmail": "richard#outlook.com",
"meetingName": "eager-plant-ignorantly-jumping",
"startTime": "1970-01-01T00:00:00.000Z",

I want to query the database with ["kate#gmail.com"] and get back the two results that have "kate#gmail.com" in the attendees field.
The closest solution (that doesn't work) is the one I found in this GitHub issue and also another close solution (that doesn't work) in this StackOverflow question
Here is me implementing those two suggestions:
import { In } from "typeorm";
async searchMeetingsByDetails(
attendees?: string[]
): Promise<IMeeting[]> {
console.log(attendees, 39);
const meetingsByAttendees = attendees
? await this.meetingRepository.find({
where: {
attendees: In([...attendees]),
},
})
: [];
return [
meetingsByAttendees,
].flat();
}
This gives me an empty array [] when the input is ["kate#gmail.com"] so if the In() thing worked, it would give results.
const meetings = await this.meetingRepository
.createQueryBuilder("meeting")
.where("meeting.attendees IN (:attendees)", {
attendees: [...attendees],
});
This one gives ERROR [ExceptionsHandler] Query Builder is not supported by MongoDB. TypeORMError: Query Builder is not supported by MongoDB.
I have a JSON that looks something like this:
{
...
"names": [
{
"value": "Name",
"language": "en"
}
],
"descriptions": [
{
"value": "Sample description",
"language" "en"
}
],
...
}
When using JsonProvider from the FSharp.Data library, it maps both fields as the same type MyJsonProvider.Name. This is a little confusing when working with the code. Is there any way how to rename the type to MyJsonProvider.NameOrDescription? I have read that this is possible for the CsvProvider, but typing
JsonProvider<"./Resources/sample.json", Schema="Name->NameOrDescription">
results in an error.
Also, is it possible to define that the Description field is actually an Option<MyJsonProvider.NameOrDescription>? Or do I just have to define the JSON twice, once with all possible values and the second time just with mandatory values?
[
{
...
"names": [
{
"value": "Name",
"language": "en"
}
],
"descriptions": [
{
"value": "Sample description",
"language" "en"
}
],
...
},
{
...
"names": [
{
"value": "Name",
"language": "en"
}
],
...
}
]
To answer your first question, I do not think there is a way of specifying such renaming. It would be quite reasonable option, but the JSON provider could also be more clever when generating names here (it knows that the type can represent Name or Description, so it could generate a name with Or based on those).
As a hack, you could add an unusued field with the right name:
type A = JsonProvider<"""{
"do not use": { "value_with_langauge": {"value":"A", "language":"A"} },
"names": [ {"value":"A", "language":"A"} ],
"descriptions": [ {"value":"A", "language":"A"} ]
}""">
To answer your second question - your names and descriptions fields are already arrays, i.e. ValueWithLanguge[]. For this, you do not need an optional value. If they are not present, the provider will simply give you an empty array.
I have requirement to get the optgroup of selected field in the query builder, but as of I am aware queryBuilder('getRules') doesn't provide. For example:- I want to get optgroups object of selected field 'price' in the json output. How to get it? Please give some idea.
-optgroups object
optgroups: {
core: {
en: 'Item'
}
}
-json output object
{
"condition": "AND",
"rules": [
{
"id": "price",
"field": "price",
"type": "double",
"input": "text",
"operator": "less",
"value": "10.25"
}
]
}
As I was answered for this question on GitHub by the library developer(#mistic100). The answer is-
You can use the data property of the filter https://querybuilder.js.org/index.html#filters
It will be copied as it on each rule using the said filter.
These is sample response of hashes in ruby.
Eg:-
find abcd1234
should give me
i was able to find by but it's not sufficent
I have response of sth like these and list keep on going different value but same structure
[
{
"addon_service": {
"id": "01234567-89ab-cdef-0123-456789abcdef",
"name": "heroku-postgresql"
},
"config_vars": [
"FOO",
"BAZ"
],
"created_at": "2012-01-01T12:00:00Z",

"plan": {

"name": "heroku-postgresql:dev"
},
"app": {
"id"=>"342uo23iu4io23u4oi2u34",
"name"=>"heroku-staging"},
},
"provider_id": "abcd1234",
"updated_at": "2012-01-01T12:00:00Z",
"web_url": "https://postgres.heroku.com/databases/01234567-89ab-cdef-0123-456789abcdef"
} .........
]
can anyone know how to grab those?
You can iterate all array element (a hash) and display its content if the hash meet your requirement:
element_found = 0
YOUR_DATA.each do |element|
if element["provider_id"].match(/abcd1234/)
element_found += 1
puts "addon_service: #{element['addon_service']['name']}"
puts "app: #{element['app']['name']}"
end
end
if element_found == 0 puts "Sorry match didn't found"
Since the elements of the array are hashes you can select the appropriate ones by matching the desired key.
select {|app| app[:provider_id] == "abcd1234"}
Do you know what to do with the element once you select it?
I think you want some of the items from the hash, but not all of them.
That might look like:
select {|app| app[:provider_id] == "abcd1234"}.map {|app| app.select {|key, v| [:addon_service, :app].include?(key) } }
I found this example where autocomplete suggestions come from external source, here it is search.php:
http://jqueryui.com/demos/autocomplete/#multiple-remote
However I don't see there how the search.php is formatted, so I get no help of getting external source to work right. I would like to get my suggestions from database and html page. Help the newbie!
The search.php return the data in the following format:
$result = array(
'query'=>$this->params['url']['query'],
'suggestions'=>$values,
'data'=>$keys,
);
query is the search query the user entered (the results are cached in hidden divs on the page)
suggestions are your results which will be displayed
data is an optional parameter which contains an array of keys matching the suggested values
The full code of the search.php file they use is also on github, here:
https://github.com/jquery/jquery-ui/blob/master/demos/autocomplete/search.php
Just look for a way to serialize objects into JSon on your platform, which should return something like this:
[
{
"id": "Dromas ardeola",
"label": "Crab-Plover",
"value": "Crab-Plover"
},
{
"id": "Larus sabini",
"label": "Sabine`s Gull",
"value": "Sabine`s Gull"
},
{
"id": "Vanellus gregarius",
"label": "Sociable Lapwing",
"value": "Sociable Lapwing"
},
{
"id": "Oenanthe isabellina",
"label": "Isabelline Wheatear",
"value": "Isabelline Wheatear"
}
