If I understand well the plainto_tsquery behaviour, this query match with:
Despite this, the president went out.
Despite the event, this question arise.
You want 'phrase search', which doesn't supported yet. There are
several workarounds, search archives for 'phrase search'
i.e., if "this" is not inside the stopwords list, the query is translated to:
SELECT id FROM document WHERE to_tsvector('english',text) @@
to_tsquery('english','despite & this');
It searches for documents which include "despite" and "this", and not for
ones which have the expression "despite this".
I have made some tests and they confirm my explanations.
Thank you anyway.
Any other solution?
