how to add search query for any keyword from title or description

[9john]

can we go like this

public class MainActivity extends AppCompatActivity {

private EditText mSearchText;
private ImageButton mSearchbtn;

private RecyclerView mList;

//firebase
private DatabaseReference mContentRef;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mSearchText = (EditText) findViewById(R.id.searchTextView);
    mSearchbtn = (ImageButton) findViewById(R.id.searchBtn);
    mList = (RecyclerView) findViewById(R.id.listView);
    mList.setHasFixedSize(true);
    mList.setLayoutManager( new LinearLayoutManager(this));

    //firebase database reference of content we are search
    mContentRef = FirebaseDatabase.getInstance().getReference().child("Content");

    mSearchbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //get the text from the edit text as string into a variable searchText
            String searchText = mSearchText.getText().toString();

            //pass the variable search text in the method searchText
            firebaseSearch(searchText);
        }
    });



}


//here we declear a method to carryout the search and display it in recycler view
//using firebase ui recycler adapater
private void firebaseSearch(String searchText) {


    //declear a firebase query to retrieve the search text,
    //start at the letter typed and end at the letter typed
    //
    Query searchQuery = mContentRef.orderByChild("title").startAt(searchText).endAt(searchText + "\uf8ff");

    /*
    * FirebaseRecycler add accept the model claa and view holder class
    * also we pass in four arguments:
    * the model class , the single item layout, the view Holder class and the search query
     */
    FirebaseRecyclerAdapter<Search, ContentViewHolder> fireAdapter = new FirebaseRecyclerAdapter<Search, ContentViewHolder>(
            Search.class,
            R.layout.item_layout,
            ContentViewHolder.class,
            searchQuery


    ) {
        @Override
        protected void populateViewHolder(ContentViewHolder viewHolder, Search model, int position) {

            viewHolder.setContents(model.getTitle(),model.getDesc());
        }
    };

    mList.setAdapter(fireAdapter);
}


//View holder class
//we set the contents to the view widget

public static class ContentViewHolder extends RecyclerView.ViewHolder{
    View mView;
    public ContentViewHolder(View itemView) {
        super(itemView);
        mView = itemView;
    }
    public void setContents(String title,String desc){
        TextView titleText = (TextView) mView.findViewById(R.id.titleText);
        TextView descText = (TextView) mView.findViewById(R.id.DescText);

        titleText.setText(title);
        descText.setText(desc);
    }


}

}

and search.class as

public class Search {

private String title;
private  String desc;

public Search() {
}

public Search(String title, String desc) {

    this.title = title;
    this.desc = desc;
}

public String getDesc() {
    return desc;
}

public void setDesc(String desc) {
    this.desc = desc;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

}
