Hello hackers,
I would like to propose nepali snowball dictionary patch.
Nepali is inflectional and derivational language. And it can be stemmed.
initdb also patched, so it can determine default text search
configuration.
Examples:
=# select ts_lexize('nepali_stem', 'लेख्');
ts_lexize
-----------
{लेख्}
=# select ts_lexize('nepali_stem', 'लेखछेस्');
ts_lexize
-----------
{लेख}
=# select ts_lexize('nepali_stem', 'लेखे');
ts_lexize
-----------
{लेखे}
Authors:
- Oleg Bartunov
- Nepali NLP Group
Is it appropriate to add new snowball dictionaries? I'm not sure about
policy of including new snowball dictionaries.
