Re: Tsearch2 ranking

Order of terms in ts_query hasn't any meaning in current implementation. But you can use your own ranking function.

2 rows of tsvector:

'bar':2 'baz':3 'foo':1
'bar':2 'baz':1 'foo':3

so source text was:

foo bar baz
baz bar foo

ts_query now is 'foo&baz&baz', so both matched.

How can I honor the correct order of the first row and rank it higher? The position information is there, why doesn't rank() / rank_cd() not use it?

Is there any way to make a difference between those to rows? Any? Even if it's a bad hack? I really need it :/

Thanks in advance
