Bibtex filter is not getting all the authors of the bib file

[AlaaHamoudah]

I use bibfitler shortcode with author params

[bibfilter author="K. hhhh|P. mmm" file="" template="av-bibtex" format="av-bibtex" group="year" group_order="desc" sortauthors="0" allow="inproceedings,article,misc" ]

This will result to show 3 options in the select author (K. hhh, P. mmm and All), All here is a combination of the 2 authors, what if the file has 100 authors and I need to search with specific authors ( for example top 10 authors)? How can I show all users even if they are not listed on the author's param?
