Full-text Index stop list for Persian language

Question

I need to customize Full-text search for Persian language. And customize Stop/Noise words and synonyms for this language.

My SQL Server version is 2016 and full-text search is installed.

Answer 1

For use Persian language in SQL Server Stop list, Full text catalog and etc just we should use Neutral. If you don't use Neutral in catalog I suggested for you change it to Neutral, sometimes this is empty like below:

Your problem solve by this query for any language:

--View Stoplist word
SELECT w.stoplist_id,
   l.name,
   w.stopword,
   w.language
FROM sys.fulltext_stopwords AS w
   INNER JOIN sys.fulltext_stoplists AS l
     ON w.stoplist_id = l.stoplist_id;

-- Stopwords list
CREATE FULLTEXT STOPLIST StopListCustome;
GO

-- Add a stopword
ALTER FULLTEXT STOPLIST StopListCustome
    ADD 'SQL' LANGUAGE 'English';
GO
ALTER FULLTEXT STOPLIST StopListCustome 
    ADD 'از' LANGUAGE 'Neutral';
