Question

I am little confused that, how to use AND-OR operators in SOLR search query.

In above URL, I want to make a query like:

(category_name:kithcen AND reno_wall_colours:red) or (category_name:bathroom AND reno_wall_colours:red).

Answer 1

((category_name:kitchen OR bathroom) AND reno_wall_colours:red)
