FTS - Restricting returns error

[cmfy]

After restricting a full text search, I get the following error:

calibre, version 6.2.1
ERROR: Invalid search query: The search query: gut was not understood. See <a href="https://www.sqlite.org/fts5.html#full_text_query_syntax">here</a> for details on the supported query syntax.
Failed to parse search query: gut with error: SQLError: too many SQL variables

Last version on which I haven't seen that happen was 6.1.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
