Hi,
Thanks for your feature request here.
it is possible to create a search box that only searches in certain categories. My intention due to the large number of files by category I have is to create a search engine that only searches in a certain category, it does not help me to choose the category of the drop-down since I have many (in addition there are categories that I do not want to appear in the drop-down), and the drop-down is very large.
This is something we have planned for a future major release: version 4.6 (we are currently in version 4.5).
Though it’s hard to give a precise date on new features release for various reasons.
It mainly depends on the development roadmap we've defined for the developer and problems we may encounter during this period
Cheers,
