This is due to the lucene query syntax and its special chars (+ - &&
|| ! ( ) { } [ ] ^ " ~ * ? : \)
see http://lucene.apache.org/java/2_4_1/queryparsersyntax.html

There must be some problem somewhere else If you escape you
querystring "copy-n-paste" and you have KeywordAnalyzer for search and
indexing there should be a result.
try this:
RAMDirectory r = new RAMDirectory();
IndexWriter w = new IndexWriter(r, new KeywordAnalyzer(), true,
MaxFieldLength.UNLIMITED);
Document d = new Document();
d.add(new Field("f", "copy-n-paste", Store.NO, Index.ANALYZED));
w.addDocument(d );
w.commit();
KeywordAnalyzer ana = new KeywordAnalyzer();
QueryParser p = new QueryParser("f", ana);
IndexSearcher s = new IndexSearcher(r, true);
TopDocs search = s.search(p.parse(QueryParser.escape("copy-n-paste")),10);
System.out.println(search.totalHits);
