>          Components: FUN - Functions
>    Affects Versions: 0.9.4
>            Reporter: Ali Alsuliman

> Fix matching a literal backslash in LIKE. As an example,
>   
> {code:java}
> SELECT "test\\string" LIKE "%\\\\%"
> {code}
> Also, fix the issue with a dynamic and changing pattern in regexp_*() functions (and functions using regex matcher class). Here is an example, for a dataset with the below tuples
> {code:java}
> { "id": 1, "test_str": "hello world", "pattern": "h"}
> { "id": 2, "test_str": "hello world", "pattern": "H"}
> FROM ds SELECT regexp_contains(test_str, pattern, "i"); -- "i" flag means case insenstive{code}
