KeywordAnalyzer
Hello,
I am using KeywordAnalyzer for one of the fields and have problem with it.
When my original term has not English characters as well as - & \ /.
Is there any alternative for this. Or how to solve the issue with
characters?
Thanks

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);

Hi,
I have docs in my index like:
name: open & close
name water fall\
name: play-end-go
I am using KeywordAnalyzer to index docs and for querying
term: play-end-go
Query qp= new QueryParser("name", new KeywordAnalyzer()).parse(term);
After I am doing this I am getting error about - and if my term contains &
or \ no results
I tried to use QueryParser.escape(); before passing into parser. I am not
getting error during quering but not result is found
