since V12, the search filters for link fields have changed in a way which makes it hard to find the right match.
A simple example: when switching the language to English, I enter “en” in the language field:
There are many languages that contain “en”. Luckily, in this case, en is still in the list. We have other examples with more data (e.g. item groups), where you can’t find the actual value, which for the user is very confusing. There is a workaround by just typing and then leaving the field. But you have to be confident enough that the value is right…
I propose that the algorithm should have an exact match always as first option (I think that was like this in the past…); E.g. refer to https://stackoverflow.com/questions/31315669/how-to-use-mysql-like-with-order-by-exact-match-first
