Ineffective search for the "simpleQueryString_" predicate. The SimpleQueryParser class requires the "flags" parameter in the constructor. Currently, the "flags" parameter is set to "-1", which means that the operation of this predicate does not differ from the "match" predicate. Unfortunately, this makes the predicate completely useless. The correct operation of SimpleQueryParser depends on the settings of these flags, however it is not possible to set them by defining predicates.
