> This patch adds some pattern matching operators, such as ILIKE, SIMILAR TO, REGEX operators,
and improves LIKE operator. In addition, it improves null handling on those string pattern
matching operators.
> Also, I've added the manual to the query language wiki page (https://wiki.apache.org/tajo/QueryLanguage#PatternMatching).
