Message-ID: <18580-11fe381a9adde140@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18580
Logged by: Karan Bosamia
Email address: bosamia.karan@gmail.com
PostgreSQL version: 14.10
Operating system: Ubuntu
Description:
SELECT *
FROM (
SELECT
*,
similarity(provision_clean_description, 'Policies The General Partner
shall promptly notify the Investor of any proposed changes in the Funds
leverage policies including adjustments to leverage ratios') AS sim_tim
FROM provision_database
) pd
WHERE sim_tim <= 1 and sim_tim > 0.7 and firm_id=18;
This both sentences giving similarity score as 1 despite the fact that the
sentence 1. has Policies as the starting word(do not include the starting
hyphen in the sentences):
- Policies The General Partner shall promptly notify the Investor of any
proposed changes in the Funds leverage policies including adjustments to
leverage ratios
- The General Partner shall promptly notify the Investor of any proposed
changes in the Funds leverage policies including adjustments to leverage
ratios
