Postgresql full text search part of words

Question

Is postresql capable of doing a full text search, based on \'half\' a word? For example I\'m trying to seach for \"tree\", but I tell postgres to search for

Sounds like you simply want wildcard matching.

• One option, as previously mentioned is trigrams. My (very) limited experience with it was that it was too slow on massive tables for my liking (some cases slower than a LIKE). As I said, my experience with trigrams is limited, so I might have just been using it wrong.

• A second option you could use is the wildspeed module: http://www.sai.msu.su/~megera/wiki/wildspeed (you'll have to build & install this tho).

The 2nd option will work for suffix/middle matching as well. Which may or may not be more than you're looking for.

There are a couple of caveats (like size of the index), so read through that page thoroughly.
