Can I customize/add search filters in Knowledge Advanced

Summary:

Add advanced search filters

Content (required):

Dears,

We need to add some search parameters to knowledge tab not just searching with keywords as attached, for example we need to search with a particular criteria such as:

All docs that have attachments

All docs that under a particular category

All docs that was published yesterday

All docs that was published from a particular author

in other words we need to customize our parameters in advanced search not only working with keywords.
