Recently I have come across an annoying UX feature. I am typing a text facet and mid typing the text box is deselected. The [working] pop-up begins about a second after I stop typing. This is a large dataset over 320,000 entries.
We should probably make the below more easily configurable via a Preference setting - if you'd like that, then please open a new issue for that, or give your opinions on this older issue:
Otherwise, to workaround our default timeouts for Text Filter typing delay:
The Text Filter (TextSearch internally) has a default of .5 secs if not using Regex checkbox which itself defaults to 1.5 secs.
You can edit the text-search-facet.js file inside your installation folders and change the 500 value to something like 2000 for a 2 second delay, if that helps.
