The WPFTS Pro version you are using is very outdated. Please consider upgrading to 2.46.x which is the latest. It has a completely new indexing and searching algorithm and it should solve your issue.
Pro plugin version not able to search within other folders
I have purchased the premium version of your plugin and I cant seem to be able to search for files in directories that are not part of the media library.
https://snipboard.io/DR5Ljd.jpg this is a screenshot of my uploads folder
Is there a way to enable search within all the directories and subdirectories of the uploads folder?
Could we use this function wpfts_index_post to include all possible directories and files under the /upload folder and not just the media library folders and files?
Thank you very much in advance,
Thank you for the question!
Yes, initially WPFTS Pro was only able to search within files that are included in WP Media Library. We are developing an addon currently which will enable search by any file or file directory.
ETA of the test version is 25 Apr 2020.
