I am trying to figure out how I can introduce full text search "tips"... tips meaning, like if you start typing Mer .. then a box with a couple of words underneath comes up, with *Mercedes, Mercury *and so on :P I am thinking that the word suggestions needs to come from the already existing tsearch2 index. Words that are frequent in the index could be ranked higher as a search tip.
This could get expensive if you have a large index. You might want to summarize down to a separate (word,frequency) table. Particularly if you don't want stemming to interfere with your suggestions.
See the manuals (full text search) for details on prefix searches - introduced in 8.4 if you really want to go the tsearch route.
