> If there are mix of *AND* and *OR* filters in the query while converting the to phoenix filter from spark filters no parentheses got added to *OR* filters  which is leading to wrong filter and finally getting wrong data.
> For example if the filter is used is below
> {code}
>  where ENTITY_INSTANCE_ID = 40 and  (CANCELLATION_FLAG <> 'Y' OR CANCELLATION_FLAG IS NULL ) and CASE_MATCH_TYPE='M'
> {code}
> which is getting converted to an expression and leading to wrong result because result is always giving most of the records matching CANCELLATION_FLAG is not 'Y'
> {code}
> NOT  "CANCELLATION_FLAG" = 'Y' OR  "CANCELLATION_FLAG" IS NULL AND "CASE_MATCH_TYPE" IS NOT NULL AND "ENTITY_INSTANCE_ID" = 40 AND "ENTITY_INSTANCE_ID" IS NOT NULL AND "CASE_MATCH_TYPE" = 'M'
> {code}
