Enhance Std. Search with new field using AET

Hi all,

I need your help.

I have to enhance the standard search with new field. If I add the field using AET to the search page and check the option 'Search-Relevance', will it be enough or I will have to modify the code in the search method?

This is a new field that doesn't exist in the DB. Please explain the correct procedure to achieve this.

Thanks a lot!
