   Seeing dramatic differences in Gandiva processing time during filter 
operations for queries with a LIKE filter on a character field with a reserved 
character (-,/& etc). The version with a reserved character in the string is 
considerably slower than a similar filter without a reserved character. For 
patterns like %abc% and %ab-c%, the latter wasn't being optimized to become an 
is_substr expression because of the regex used to identify those cases.
