I'm trying to list all upcoming events for a given artist. Unfortunately, the query that i use:/search?type=event&fields=name,description,place&q=artist-name does not list all available events. It only lists the events for which the keyword "artist-name" match the field "name". To display all available events, the query must look into the "description" field in addition to the "name". How can i make such a query ?

In My database, I have a collection named 'Friends'. Inside this collection, each document represents a user. and let's say for user1, I have a field named 'friends' which is an array that contains userIDs of the friends that user1 has. In this form:
enter image description here
I followed this way instead of creating a sub-collection and represent each user by a document because I think this is more efficient in terms of documents reads when retrieving friends.
I am fine displaying friends of each user, but my problem is with implementing the Algolia search.
I have used Algolia search for searching all users but 'User' collection is different because each user is represented by a document on its own.
Thus the main question is what should I do in index.js or in the flutter code to enable full-text search using Algolia so that each user can search his list of friends for a specific name ?
Thanks.
instead of creating documents with firestore id , use name or any other known data of the user as document id so that u can easily access that document
At a high level, what I'm looking for is all of the posts a specific user has made in a group.
I can access the group feed, which contains all posts made in the group, like this:
GET 2.10/<group-id>/feed
where 2.10 is the api version I am using
I can see the author of all the posts in the feed by reading the "from" field:
GET 2.10/<group-id>/feed?fields=from
the "from" field displays a user, which is represented as a JSON object with two properties:
"from": {
"name": <user_name>,
"id": <user_id>
}
some collections have "read modifiers", for example on a feed that belongs to a person's profile, you can filter for only posts that have locations attached to them:
GET 2.10/me/feed?with=location
It seems a "read modifier" on the group feed would be what is needed, however none are documented: https://developers.facebook.com/docs/graph-api/reference/v2.10/group/feed
Is there any way to filter the feed so that it returns only posts by a specific author?
rephrased more generally:
is it possible to filter a collection of nodes by a node attribute?
is there another possible way to query for posts made by a specific person in a specific group?
I'm a MongoDB newbie, but have gone through some basic trainings. However, I'm not able to handle this (seemingly simple) situation:
I'm populating my database with results from two API calls. The first call returns a bunch of fields that include a primary key: NAME. The second call gets additional details for each NAME. I've inserted the results of the first call into the database. When I do the second call, I want to update the document with the matching NAME to include all the additional fields and values returned by the second API call. (ex. the first call returns a recipe NAME and a bunch of metadata about the recipe; the second call returns a list of ingredients, and I want to add those to the document for that recipe based on the matching NAME).
Shouldn't this be easy? Or does this constitute a merge, which I believe mongo does not support? In that case I assume I just insert the second call's results as a separate document and do future queries on NAME in order to pull both documents relating to that NAME?
You have to use db.collection.update() call to get it done. What you do in this is that you pass in the query to locate the right document, in your case it is NAME, and then update the document appropriately.
Ex: Let's say the NAME be updated is 'eamcvey' and you want to put in Address and Phone Number field. The command you would type in for that would look like:
db.collection.update(
{NAME : 'eamcvey'},
{
$set : {Address : 'Updated Value of Address'},
$set : {PhoneNumber : '123456'}
},
);

I'm toying with the Github search API (v3) and can't seem to find a description of the fields that are returned. Most of them are obvious, but there are a few like score that aren't. Does anyone know what score means, and does a field reference exist?
The score attribute is the search score of that document for a particular query, and is used for Best Match sorting. In other words, it's used for ranking search results, but it isn't shown in search results on github.com.
I am using Solr to index documents from a wiki. Each document has a unique id, title, body content and some other fields.
Firstly, I wanted to know the declaration in the Solr schema to store the multivalued field "tags" to hold n of these strings, attached to the document. Each document can have a set of tags applied on it.
Second, the use case - how exactly would I retrieve all distinct tags across the entire Solr instance with number of occurences, so that I can build a tag cloud of most popular tags?
thanks
