3522838 - Fuzzy Text Search with a period in the search term scores differs in case sensitivity vs case in sensitivity

Issue is when same keywords are used in upper case and lower case in combination with a "period" . ,  getting different results. Whereas this shouldn't impact the hits result for same alphabet i.e. "sl." and "SL.". 

SELECT

            TO_DECIMAL(SCORE(), 3, 2) AS score, *, CAST(HIGHLIGHTED(companyname) AS NVARCHAR(250))  AS mch_kws

FROM

            table1

WHERE

            CONTAINS(companyname, 'SL.', FUZZY(0.5, 'textSearch=compare,andSymmetric=on,composeWords=2,spellCheckFactor=0.6,minTextScore=0.5,andThreshold=0.51'))

ORDER BY

            score DESC, ID;

Search for ‘SL.’, score is 0.7

Search for ‘sl.’, score is 0.83

What is the logic for upper case and lower case in combination with a "Period" in Fuzzy Text Search?

From the above the score should be the same .
