thanks; I have added your mappings and uploaded a new stable snapshot
[1,2]. The following query should now return true:

  "ά" contains text "α"

Next, I've added the Greek stemmer to our internal implementations. It
can be invoked by setting "stemming" and "language"; e.g.:

  "..." contains text "..." using stemming using language "el"

Due to my non-existing Greek language skills, I'm sorry I had no
chance to perform any tests.. your feedback is welcome!

In this particular case, you can switch off the removal of diacritics via..

  "ά" contains text "α" using diacritics sensitive

That's true. I'll write some more on that as a reply to Michael’s mail.
