Re: nulls in GIN index

Perhaps I'm missing something

Table has 2 columns, text and ftstext

text: "how are you"
ftstest: (nothing)

Because "how" and "are" and "you" are too common to be tsvectored. Which is
fine.

So if a user searches for "how are you":
select * from tbl_lines WHERE
ftstext @@ plainto_tsquery('English', 'how are you')

Returns nothing. Which I somewhat understand, but I want it to return all
the rows with nothing in the ftstext.
plainto_tsquery('English', 'how are you') = ''
and the ftstext of some rows is also = ''
So why doesn't the index return all these rows when a null string is
searched.

I think you can see what im trying to achieve, how do I do it?
