Is it possible to make such a filter using standard means of the dle engine?

Question

DLE

Site
mot.com.ua
site is built on dle
functionality does not cause questions
catalog is built with add. fields, which does not cause any difficulties with the standard functions of the engine to do all this
, the filter is more interested (search on the main page by fields)
Is it possible to make a filter using the standard means of the dle engine? so as not to put third-party crutches and not pick the engine
