I am currently using the prefix search feature in text search. I find
that the prefix characters are treated the same as a normal lexeme and
passed through stemming and stopword dictionaries. This seems like a bug
to me.
db=# select to_tsquery('english', 's:*');
NOTICE: text-search query contains only stop words or doesn't contain
lexemes, ignored
to_tsquery
------------
(1 row)
db=# select to_tsquery('simple', 's:*');
to_tsquery
------------
's':*
(1 row)
I also think that this is a mistake. It should only be highlighting "s".
db=# select ts_headline('sushant', to_tsquery('simple', 's:*'));
ts_headline
----------------
<b>sushant</b>
Thanks,
Sushant.
