> There is a problem with query parser when search string starts/ends with ||.  When string
contains || in the middle like 'something || something' everything runs without a problem.
> Part of code: 
>   searchText = QueryParser.escape(searchText);
>   QueryParser parser = null;
>   parser = new QueryParser(fieldName, new CustomAnalyser());
>   parser.parse(searchText);
> CustomAnalyser class extends Analyser. Here is the only redefined method: 
>     @Override
>     public TokenStream tokenStream(String fieldName, Reader reader) {
>       return new PorterStemFilter( (new StopAnalyzer()).tokenStream(fieldName, reader));
>     }
> I have tested this on Lucene 2.1 and latest source I have checked-out from SVN (Revision
538867) and in both cases parsing exception was thrown.
> Part of Stack Trace (Lucene - SVN checkout - Revision 538867):
