[Proposal] Configurable number of characters to start the search

[jarofromel]

Currently the search starts when I type at least 4 characters. It would be nice to have option where I can set this.
Self-ish reason:
I frequently use 3 character flags/signs in my notes.
(gwd - google keyword, sbs - step by step, lll - list of lists of lists etc)

Not so self-ish reason:
My usage experience (other search engines, completion mechanism) is the search usually starts after I write 2 or 3 chars.
I almost wrote the issue at the time of beginning with orgro that the search does not work (I spent several minutes writing different 3 chars keywords until I wrote something with 4 chars).

Search is very computationally costly, so for performance reasons I chose 4 characters as the threshold for incremental search. However you can force the search to proceed at any time by pressing the Search or equivalent key on your keyboard (on Gboard it appears to be a 🔍 icon; for a hardware keyboard it's probably the Enter key).

I'm not inclined to add a setting for this because this falls under the umbrella of things that should just work. I would consider:

• Dynamically adjusting the threshold based on device performance. I don't know of any reasonable way to measure device performance, though.
• Optimize search/render performance enough that it's feasible to lower the threshold

Thank for the explanation. The trigger to force the search is good enough for me. As I said it was mainly the matter of UX based on past experience. I think a bit of search detailed behavior described in the doc could be helpful: Live search (highlighting the search hits as you type) starts after typing 4 chars if you want to trigger the search earlier, hit the search button

The other solutions you outlined seems great.
I know this exists https://developer.android.com/topic/performance/performance-class and the Android device should declare its performance class. However I don't have any experience with it.
