Recoll is a desktop search tool.
Starting from about version 1.26.6 GUI started lagging a lot.
A simple solution: use TUI.
This tool is <100 lines in bash and uses fzf.
Clone the repo and make a symbolic link to the recoll_tui file in
your PATH.
recoll_tui is the "main" file. There one can add key bindings.
Other files are for my own convenience.
