Applying Word Stemming in SearchView for fetch data from Firebase database

问题

I need to fetch list of users from Firebase database using SeachView or search dialog and I think word stemming will be best for my app.

Not asking for code but please tell me the alorigthm for it.

To achieve what you want, you need to execute a query which should look like this:

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference usersRef = rootRef.child("users");
Query query = usersRef.orderByChild("name").equalTo(newText);

So everytime you create a search you should return a new query. So according to this, every time you want to filter on a new condition, you will need to:

1. Create a new query based on the new filter:

   Query query = usersRef.orderByChild("name").equalTo(newText);
   

2. Attach a listener to this new created query.

3. Create a new adapter with the results of this new created query, or update the existing one using notifydatasetchanged() method.
