Subject: BUG #17043: Full text search - to_tsvector treating a full stop wrong
Date: Wed, 02 Jun 2021 10:04:59 +0000
Message-ID: <17043-03f93dfe629bcc1b@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17043
Logged by: James Inform
Email address: james.inform@pharmapp.de
PostgreSQL version: 13.3
Operating system: Mac and Ubuntu
Description:
It seems that to_tsvector is treating full stops wrong. If a sentence end
with a '.' and the following word isn't separated by a space, to_tsvector
will identify it as one lexeme:
select to_tsvector('english','This is the rat.Fat is she!')
'rat.fat':4
select to_tsvector('english','This is the rat. Fat is she!')
'fat':5 'rat':4
select to_tsvector('english','This is the rat.Fat is she!') @@
websearch_to_tsquery('fat')
false
select to_tsvector('english','This is the rat. Fat is she!') @@
websearch_to_tsquery('fat')
true
