I do not know is this BUG or regional settings misunderstandings but in serach box when user type word letter by letter if 4TH letter is βYβ serach box shows blank
If I copy and paste full string at once search box will show correct rezults.
Forgive me if Iβm boring but looks like that this is not just case with Y letter.
Perhaps Discourse trying to search for words
Here is also sample whit word silent will match silently
but when user just types silentl Discource will not match silently.
I have been considering using ispell instead. Since you are a non-English install its very likely the English stemmer is a bad choice and you should just go with simple or a language specific stemmet.
It will require mucking with the install a bit.
Long term I am thinking of doing all the stemming and stopword in our ruby process to avoid all the magic done in pg.
