Remove Keyword Requirement in Advanced Search

[textbook]

Hello,

 

Currently, my advanced search requires that I enter a keyword and then click search.

I also have the option to filter this search by category, manufacturer, date, and/or price.

 

I would like to remove the requirement for the user to enter a keyword into the search.

This way, they can just search by filtering from the options, press search, and see all of the items pertaining to those options (without entering a keyword).

 

Does anyone know how to do this or can help me out?

I would really appreciate it!

 

Thanks.
