Amit Gupta commented on JCR-4042:
---------------------------------
[~julian.resc...@gmx.de] IUC, do we just need escape character for colon. As
colon is the only special character for current gql implementation. If we have
escape character for colon, then we don't need to use quote and thus no
escaping for quotes.
> Adding Escape Character in GQL

> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-jcr-commons
> Reporter: Ankit Agarwal
>
> Currently GQL does not have a escape character. Adding the escape character
> will help in special character cases for example where a search term contains
> both colon(:) and quote(") character.
> for example search string is foo:bar, if term is put in quote "foo:bar" and
> this whole term is considered as a single search value.
> But in case user need to search foo"abc:bar then putting this term in quotes
> won't work. But if GQL will have a escape character, then user can search
> this term using escape character.
