Thanks you so much. It is really helpful article and I wanted this to search for an item that may exist multiple colums in a database. One improper approach here is, it requires to provide multiple or copy of keywords for all colums to be searched in it. Like this:
String fields[] = {”color”,”details”};
String keywords[] = {”white”,”white”};
This could have been made to provide single keyword over multiple fields, but unfortunately it is not possible. Anyway its ok and serves better 
Thank you!
