Subject: BUG #18636: I am seeing a difference in behavior between 13.12 and 15.6 for full text searching
Date: Fri, 27 Sep 2024 13:28:18 +0000
Message-ID: <18636-3f0e3fe4e7ac0b1c@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18636
Logged by: Glenn Cipolla
Email address: glenncipolla@gmail.com
PostgreSQL version: 13.12
Operating system: Ubuntu 11.4
Description:
The following query
select to_tsvector('simple','RG147SW RG14 Greenham Road Newbury West
Berkshire')
@@ to_tsquery('simple', 'gree,west:*');
Returns false in PG 15.6, but returns true in pg 13.12. In 15.6 the code
returns 'gree:* <-> 'west':*.
In 13.12 it returns 'gree:* & 'west':*
This article says the 13.12 behavior was a bug that was fixed in 14.x
(https://akorotkov.github.io/blog/2021/05/22/pg-14-query-parsing/).
I have a dev team about to change their code to handle the new <->. Before
they do that, I would like a confirmation that this functionality is
1. A bug
2. The new functionality will not change back in newer versions. Do you
intent to stick with the <-> return value?
Thanks,
Glenn
