2. Check nothing is displayed but at magnolia-debug.log and error has been registered

Development notes

According to Jackrabbit specification, some special chars as single quote ("'"), double quote (""") and hyphen ("-") must be escaped with a backslash ("\"). Would be nice if we could scape that search on backend or at least, show a warning to the editor to let him know that regarding the JCR specification a slash must be added to the search.
