Hello,
I have the following table:
so2, which has following column details:
|id, title, posts, body (tsvector). |
And I created the index on the following:
|"so2_pkey" PRIMARY KEY, btree (id)|
|"body" gin (body)|
And I wanted to query on my tsvector with the string: `Is it possible
to toggle the visibility of an element`. I tried the following query:
If you want phrase search, use the phraseto_tsquery function, like
phraseto_tsquery( 'Is it possible to toggle the visibility of an
element')
or
phraseto_tsquery( 'my_ts_config', 'Is it possible to toggle the
visibility of an element')
|SELECT id, ts_rank(body, keywords) AS rank|
|FROM so2,|
|to_tsquery('Is & it & possible & to & toggle & the & visibility & of
& an & element')|
|keywords|
|WHERE keywords @@ body ORDER BY rank DESC;|
This give the result in which the "element" string count is large in
number, however there is a record which exactly matches the search
string, that comes as third in my result. So logically it just checked
in my query which word count occurs the most across my body column,
which I don't want.
Can I say somehow to postgresql, that I want the pharse search rather
than the text spilt up weight in the document. Is it possible to do?
Edit: I tried with `|ts_rank_cd\|` as well. Same result.
