Re: hunspell and tsearch2 ?

Hi Robert,

there is a note in the pg documentation chapter

12.6.5 Ispell Dictionary

*Note:*MySpell does not support compound words. Hunspell has
sophisticated support for compound words. At present, PostgreSQL
implements only the basic compound word operations of Hunspell.

Regards
Dirk
