I want to make the default wordpress search more advanced like adding categories, let's say for example : "best products", " good products" and a lot more .

I know there are some plugins which can improve the search query like to be able to search through tags, custom taxonomies like " Search everything".

Basically what I need is to be able to get tags from custom post types or blog posts to act like categories for the search form, like advanced search for example have a drop down list with some tags.

Do you know a plugin which can help me making this  ?

I want to make the default WordPress behave better. For instance, if I add categories such as: "best products", "good products" and more then the search should be able to account for those and return them higher in the results.

I know there are some plugins which can improve the search query like to be able to search through tags, custom taxonomies like "Search everything".

In short what I need is to be able to get tags from custom post types or blog posts to act like categories for the search form, perhaps an advanced search with a drop down list with some tags.

Do you know a plugin which can help me do this?
