Description
Doing an indexed search for certain Unicode characters causes a program crash. In these, and probably other cases, the Clucene QueryParser::parse call returns null. This causes an unhandled exception because the return value is not currently being tested. A simple fix would be to test for null in swmodule.cpp after line 511 (q = QueryParser::parse...) and do nothing if its null.
For example, doing an indexed search for "←" (without the quotes) causes a crash.
