1. "K2 Filter and Search module" will search in tags and author : great !
2. I have set : Filter parameters > Select filter fields > Keyword (Item all in one)
Search results Ordering>Default ordering>Title
Let's take the case where I have 3 items:
Like an apple
If "apple" is searched, the search results will find 3 results (which is good) but will not display ID 1 and 3 first. Ideally search result should be ID 1,3,2 (because the later has apple in intro text and not in Title)
