Answer 1

Answer : simply do following query :

databaseReference.orderByChild('_searchLastName')
 .startAt(queryText)
 .endAt(queryText+"\uf8ff");

We can combine startAt and endAt to limit both ends of our query. The following example finds all dinosaurs whose name starts with the letter b:

curl 'https://dinosaur-facts.firebaseio.com/dinosaurs.json?orderBy="$key"&startAt="b"&endAt="b\uf8ff"&print=pretty'

The \uf8ff character used in the query above is a very high code point in the Unicode range. Because it is after most regular characters in Unicode, the query matches all values that start with a b.
