[digiKam-users] [FR for usability]: Default search mode visible

Rafael Linux
Hi

Last year I discussed here about the convenience of disable "auto searching"
just in single search when the user type any letter or if some search was
done previously and the user open the "Search" tab. On large databases it
hangs DK. In DK 6.1 I was presuming it was changed, but it is not. You
implemented a hidden and not very intuitive way to disable the "autosearch".
I needed to search in this forum to find a way to do it
(http://digikam.1695700.n4.nabble.com/digiKam-users-dk6b3-searches-td4707224.html#a4707235).
So, please, to avoid headaches for users with large databases, could you
change the option to "DK configuration, Others, Search" or even a button
next to the search cell with "Search with enter" enabled by default, or even
simply a "Search" button. Any way that let user choose when the search must
begin.

Thank you

It's not just large datasets, even medium one. The problem is the
thumbnails. DK is retrieving the thumbnails for the images that
qualify for the "as is" search.

+++++1

It would make DK much more responsive.

The other problem is that DK remember the last search and tries to
execute it when I enter the search tab.

* If after the search I close DK.
* If the last search was a very large dataset, something like almost
  almost all the images. Starting DK will "take forever" because not
  only it's checking for the new images, but it's also executing the
  search from the last time (which I don't need anymore).
* DK doesn't like having the search interrupted. More often than
  not, DK would crash if I interrupt the search.
* I've had to learn to live with the very slow starts because I
  exited DK after a search. Now I try to remember to switch back to
  albums before exiting.

How big are your databases? I'm managing ~100000 pictures and I haven't had
any problems with slowdowns in searches. Only in the timeline view it takes
a while when several years are selected.

For me it, it's the search. I never use the timeline

In reply to this post by woenx
+300K with MySQL and SSD and, as digikam-2 wrote, is the search. A large
database with commentaries and plenty of metadata for more than 85% of
images, logically will drown CPU if the searching begins just even without
typing nothing and then you just begin to type while CPU is busy. Then DK
will stop respond, freezing for many time (even 5 minutes or more) till it
shows the searching results.
