getUserTokens api should return all tokens which are matching either of the same metadata name passed as query param

Steps:
1. Create token1 with md_Name=reina&md_Score=50
2. Create token2 with md_Name=mary&md_Score=100
3. Create token3 with md_Name=mary&md_Score=20&md_Grade=A

Scenario 1:
Fetch token with "md_Name=mary&md_Score=100"
Result : returns token2 and token3

Scenario 2:
Fetch token with "md_Name=mary&md_Name=reina"
Result : return token2 and token3

Expectation:
if the api returns all matching tokens of any of the mentioned metadata in query param , then i would expect scenario2 to return me token1,2,3 though the passed metadata name in query param ("Name") is same but with different values. But here it doesnt return token1
