No Greek stop words in FTS ?

Hi,

I maintain a project (diofanti.org <http://diofanti.org/>) that tracks public spending in Greece.
It’s a PG instance hosting 55M+ json documents with searching functionality on top of them.

It relies heavily on to_tsvector(‘greek’, ..), as users search for company names, invoice descriptions etc.

The results are fairly good, but as I was trying to experiment with adding some more domain-specific stopwords, I realised there’s no greek.stop under $(pg_config —sharedir)/tsearch_data
And indeed looks like stop words are maintained with to_tsvector(‘greek’, ..).

select to_tsvector('greek', 'ΚΑΛΗΜΕΡΑ ΚΑΙ ΣΕ ΕΣΑΣ'); --> 'εσ':4 'κα':2 'καλημερ':1 'σε':3
select to_tsvector('english', 'AND GOOD MORNING TO YOU TOO'); --> 'good':2 'morn’:3

I found an older discussion on pgsql-hackers [0] but not sure where this stopped / if started ?

Am I missing something?
Is there another thread/patch I can peek up myself ?
