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.
