Here is a code for searching text:

        Analyzer analyzer = GetAnalyzer();

        QueryParser parser = new QueryParser("Text", analyzer);         
        parser.SetAllowLeadingWildcard(true);
        Query query;        

            query = parser.Parse(finalSearch);

        Hits hits = searcher.Search(query);

And Here is a code How I am storing Text:

fieldText = new Field("Text", text.ToLower(), Field.Store.YES, Field.Index.TOKENIZED);

Try escaping your characters using '\\' . '-' will be '\\-' .

From http://lucene.apache.org/java/2_9_1/queryparsersyntax.html#Escaping%20Special%20Characters

Lucene supports escaping special characters that are part of the query syntax. The current list special characters are

+ - && || ! ( ) { } [ ] ^ " ~ * ? : \

To escape these character use the \\ before the character. For example to search for (1+1):2 use the query:

\(1\+1\)\:2
