Hi!
I'm not sure how to write a good $subject for this , but here it goes;
I'd like to have a multi-column index on a varchar-field and a
tsvector-field. GIN only likes tsvector-fields so I'm wondering if it's
possible to create a tsvector from a text which doesn't breake the text
up in vectors, but uses the whole string as the vector instead?
Given the schema:
CREATE TABLE mytable(
id SERIAL PRIMAY KEY,
field VARCHAR NOT NULL,
tsvector_col tsvector NOT NULL
);
I'd like to form a query as follows:
SELECT id FROM mytable WHERE tsvector_col @@ to_tsquery('simple',
'andre:*') AND to_tsvector('simple', field) @@ to_tsquery('simple',
'full_text_search');
And I'd like it to be semantically equivalent of:
SELECT id FROM mytable WHERE tsvector_col LIKE 'andrea%' AND field =
'full_text_search';
But I see that 'full_text_search' is broken up (of course):
andreak=# select to_tsvector('simple', 'full_text_search');
to_tsvector
------------------------------
'full':1 'search':3 'text':2
Is it a way to achieve what I'm trying here?
