title: How to search Firebase text by lower case also?
body: <p>I am using Firebase database for my Android Application. I implemented search feature in the app. On my database, every title start with "A" is showing only when I started a search with Capital "A". When I entered lower case "a" it showing no results found. I want to enable search for lower case variation also. Help me, please. Thank you. Here is my search code.</p>
  
  <pre><code>    private void firebaseUserSearch(String searchText) {
  
      Toast.makeText(Idioms.this, "Started Search", Toast.LENGTH_LONG).show();
  
      Query firebaseSearchQuery = mUserDatabase.orderByChild("Title").startAt(searchText).endAt(searchText + "\uf8ff");
  
      FirebaseRecyclerAdapter&lt;Blog,BlogViewHolder&gt; firebaseRecyclerAdapter = new FirebaseRecyclerAdapter&lt;Blog, BlogViewHolder&gt;(
  
              Blog.class,
              R.layout.bank_row,
              BlogViewHolder.class,
              firebaseSearchQuery
      ) {
          @Override
          protected void populateViewHolder(BlogViewHolder viewHolder, Blog model, int position) {
  
              viewHolder.setDetails(getApplicationContext(), model.getTitle(), model.getDescription(), model.getExample());
          }
      };
      mResultList.setAdapter(firebaseRecyclerAdapter);
  }
  </code></pre>
