As mentioned early by @sha-red, the issue search should support:

Short n-grams to allow partial matches (an issue tracker won't work without partial matching).
Not sure what is it.
Strong Unicode normalizing (because of diacritical letters).
Allows to find fällen by typing fallen.
Multi-lingual stemming.
Allows to find fallen by typing fall.
Also it should be possible to search by multiple words even when they are not near each other in the text (not sure how this ablility is called in terms of bleeve).

For example, if some issue has some english comment text in the description, then it should be able to find this issue by typing some comment in the search box. For now such issue will not be found.
