filters for search result page

Hi, i want to build filters(facets) on my search result page so that users can narrow down the search results. i couldn’t see any information how can i get facets information when i am searching my data. can you please help me to get this done?

Backendless data search is based on a concept we call “whereClause”. Any filters you implement should be able to generate different variations of the where clause.
