Database growing and queries are slow

Hello,

I have an issue on my server where siteground complaints that a query takes a lot of resource to run. The query is from this plugin

SELECT original, translated, status 
FROM ovb_trp_dictionary_en_us_el 
WHERE status != 0 
AND original != ‘<REDACTED_URL>’ 
AND MATCH(original) AGAINST (‘<REDACTED_URL>’ IN NATURAL LANGUAGE MODE ) 
LIMIT 1;

I have removed the url, it start like this: “https://outlook.live.com/owa?path=%2Fcalendar%2Faction%2Fcompose&rru=addsubscription&url=webcal%&#8221; but why it even tries to translates these url.

I have disabled dynamic translation, removed these urls from database also run the database optimization tool it helped me to reduce the data but the next day same happened.

Is there a way to only keep the data that I have translated? Remove all the rest and do not try to generate it again?

Thanks
