Full Text Search for Time

LadyLiissa82 · 04-05-2025, 11:26 AM

I'm working on an Author Clock project and would like to find instances of time within my Calibre library. I have already used the full text search for words like "midnight," "noon," etc. Is there any way to search for a generic time like a #:## format?

Edited to Add: Or even a way to just search for numbers? I'd be willing to dig through chapter titles and all the white noise if it would also capture times.

You can do that seaarching within a single book at a time using the regex search mode but not using full text search as the latter works on a pre-generated "index" of words and as such doesnt supprot regular expression based searching.

What you could do is convert all your books to TXT format and then use a tool like grep or similar to search in the resulting TXT files via the filesystem
