As per the description mentioned above, you want to know if its possible to sort the results by 'Filename' instead of 'Relevance Ranking' by default when performing an advanced search in Acrobat”, is that correct?
Sorry to say but the option to change the sorting of results when performing an advanced search is not available.
Let us know if you have any further query.
Yes, I would like to sort search results by file name as default option.
Maybe there is a workaround by setting specific Windows registry (regedit) options?
