Description
Queries using filter with sql like operator use Java regex library for pattern matching. However, for cases like %abc (ends with abc), abc% (starts with abc), %abc% (contains abc), it is observed that implementing these cases with simple code instead of using regex library provides good performance boost (4-6x). Idea is to use special case code for simple, common cases and fall back to Java regex library for complicated ones. That will provide good performance benefit for most common cases.
