Wordpress advanced search plugin

I'm looking for an "advanced search" Wordpress (widget) plugin. The included search just doesn't cut it. Will have a text field, 5 drop downs, and a submit button. All fields besides keyword optional (e.g. if user types keyword, but doesn't select category it will still search). Must search both post content and tags. Must be able to define what categories are in what dropdown. If multiple categories selected via the multiple dropdowns (e.g. category 1, category 6, category 9) it will be an "and" search (e.g. posts that are in all three of the categories) Here's what I'm looking for. [ key words ] <-- searches post content and tags (text field) [ category ] <-- select a category (drop down) - category 1 - category 2 - category 3 - category 4 [ category ] <-- select a category (drop down) - category 5 - category 6 - category 7 [ category ] <-- select a category (drop down) - category 8 - category 9 - category 10 [ category ] <-- select a category (drop down) - category 11 - category 12 - category 13 [ sort by ] <-- how posts will be sorted (drop down) - most recent <-- sort by date date - highest rated <-- sort by highest rated via WP-PostRatings (information available at [login to view URL]) - most commented <-- sort by posts with the most comments - most rated <-- sort by most rated via WP-PostRatings (information available at [login to view URL]) [ submit ] Thanks you very much!
