Understood and I agree… but how about having the software check the Restrict searched books if a VL or metadata search is active… if the user really wants to do a library wide text search whilst a metadata search is active they can uncheck it easy enough.

Four minutes to display the snippets for 250 books with nothing much else running seemed quite slow to me. It was using up to 25% of an i7-7700 with 16GB of RAM and a fair bit of HDD activity - that's why I thought it must be rattling through the format files. The full-text-search.db file is 3.51GB.

Question: Where will be the location of the search index? AppData or the library folder? I haven't tested yet to check.

Library folder - full-text-search.db

Yes, it will update normally.

But then that would mean the users choice for the checkbox is not remembered. Not sure that's better. I can think of plenty of use cases for searching full library even when the main screen is restricted. For example, to check if there are books with mislabelled data.

The snippet search has to go through the full book text, sadly the sqlite fts engine doesnt seem store offsets of words in the text, which is why it is slow. But it only needs to search the matched book files, not the full library.

Can Calibre 6 install alongside 5, or on top of it? The uninstall-to-downgrade cycle is a bit of a pain for testing.

Fair 'nuff, helps to know what's going on under the covers.

Back to hidden windows. An undocked Quickview window stays on top if I give focus to the library list window, viz:

I appreciate QV is a child window and TS is separate process (I can't Alt+Tab into QV)… but that may not be as obvious to some people.

kovidgoyal · 06-27-2022, 10:21 PM

FTS and QV are both child windows they arent separate processes.

ownedbycats · 06-27-2022, 10:27 PM

I installed the beta. It switched to light mode. I guess it's following system theme rather than the env var. Disappointing.

Any plans to make an override in look & feel? I seem to recall mention of possibly implementing it, but I can't find the post now.

EDIT: This is going to take a while...

ANOTHER EDIT: I feel like it would make sense to be able to dedicate xx CPU cores to indexing, similar to the option in preferences > miscellaneous.

I install the betas as portable versions. When the release arrives, I do a normal install.

Perhaps 'process' is the wrong term, but if they are both child windows, they have rather different behaviours… just like real children

1. QV doesn't provide a separate taskbar flyout item, TS does :

2. QV is not available as a selectable item when I press Win(or Alt)+Tab, whereas TS is:

3. If I minimise the main window, it takes QV with it, but it leaves TS (which cannot be minimised) where it is:

4. When I give focus to the main window, QV stays on top, whereas TS gets pushed down. Why can't TS behave like QV in this regard?

Did you try pressing the Fast button, my Books library indexed ~6,900 files in a bit over an hour whilst I had dinner.

Yeah, the FTS window doesn't follow the behaviour of most other Calibre child windows I've tried (preferences, annotations, jobs, undocked quickview).

kovidgoyal · 06-27-2022, 11:47 PM

Yes the FTS window is *independent* of the main calibre window, you are supposed to be able to use both simultaneously. That's by design. @BR: When restoring the main window one cannot restore the FTS window since doing so would mean on a small screen the FTS window would always cover the main window.

That said, the I will look into adding minimize/maximize buttons to the FTS window titlebar. SHould be a simple flag to pass to Qt.
