My understanding about fuzzy search. However not sure if this info may help you.
A fuzzy search can help you seach records even if the search contains additional or missing data with spelling errors.
Fault-tolerant will help you search in text columns or check for duplicate records.
SQL syntax to search
select * from <<your tablename>> where contains (<<column_name>>, "search_string", FUZZY (0.8))
There is scording system where 1.0 is exactly match to 0.0.
Not all data types are supported.
