I need to build a better search engine for one of my sites (which is non-q2a).
I know that q2a has its own search engine and search logic. Guess, most of you are satisfied with that?
The qa_db_search_posts_selectspec() looks quite complicated... and seems that table qa_words is used a lot. But before I am getting lost in details:
How does the Search module of q2a work basically?
