Process Interrupt for Calibre Search Error ?

Rob557 · 03-14-2019, 03:57 PM

Whenever an error is made in the syntax for a Calibre library search (e.g. today I accidentally mistyped the "t" resulting in "yiyle:" when I was trying to search for a book by its title), the Calibre search process just hangs for an indefinite time period. My quick-fix has been to terminate and restart Calibre.
Two questions:
1. Are there any keystroke shortcuts that can immediately abort a faulty search request ?
2. Just curious what Calibre is actually doing when the search syntax is invalid, and why Calibre doesn't just immediately generate a null result or error message?
Thanks.

It is not a syntax error since you could have a value in one of your searchable columns that is equal to "yiyle:mytitle". If you have a huge number of books and many Tags, Comments, and custom columns, especially Tag-Like CCs with thousands of tags or with comments CCs with large amounts of text, I could see how it could easily take a very long time to search through all of your metadata for the string "yiyle:mytitle".

Preferences > Searching > Limit the searched metadata.

Thanks DaltonST. That explains why the process could takes a long time.

Some sort of process-interrupt would then be helpful, when a user realizes they have messed up on a search request.

Thanks

Esc key doesn't work?

@Rob557 - you must have a humongous amount of metadata, how big is metadata db?

I often type gobbledygook deliberately in the search line to get a blank list, even on my 130K+ book library it comes back almost instantly with nothing in the list. I don't have any limits on search.

Lol, my library's much smaller (~5500 books, 40 custom columns) and search is pretty instantaneous here, too.

Thanks "ilovejedd". The Esc key DOES seem to work to stop the processing ... not immediately (I pushed it multiple times, but probably not necessary) but fairly quickly. THANKS !

I guess sometimes the faulty search process lasts longer than one would expect (when not using the Esc key) because I probably had other applications running at the same time ... so maybe not just related to the size of the library (and I'm an impatient fella sometimes I guess).

Thanks all for your help and info on this.

How much RAM do you have and are you on HDD or SSD? If your RAM is full and you're constantly hitting the page file on an HDD, I can easily imagine the system becoming unresponsive.

Also:
The Library must not be on a NAS or share or ACTIVE sync (sync should be paused while using Calibre GUI)
