Comment 13 for bug 1929325

Ref: https://github.com/kovidgoyal/calibre/commit/d8752252e61d36a249923b59ef5f524f62f1a393

And surrounding changes. Note that calibre now includes a SQLite fts plugin based on ICU and libstemmer.

Since all the C/C++ changes.were present in the latest release (5.22), you should be able to follow the calibre manual's development guide to plug in the python sources and test this out in development mode.

Then you could check if it works, and if not, offer additional improvement suggestions ahead of the general public release?
