Query search for exact word

[peliukasss]

Hello,

Can anyone tell me this:
How can I search a word and only specified word.
For e.g: I have a word house. And I need to search only for it, not for for e.g houses.

My search looks like this:

            analyzer = new StandardAnalyzer(Version.LUCENE_30);
            File file = new File(indexDirectory);
            directory =  SimpleFSDirectory.open(file);
            Searcher isearcher = new IndexSearcher(directory, true);

            QueryParser parser = new QueryParser(Version.LUCENE_30, "fieldname", analyzer);
            Query query = parser.parse(word);
            
            TopScoreDocCollector collector = TopScoreDocCollector.create(500, true);
            isearcher.search(query, collector);
            System.out.println("Hits = " + collector.getTotalHits());

            ScoreDoc[] hits = collector.topDocs().scoreDocs;
            Document hitDoc = null;
            for (int i = 0; i < hits.length; i++) {
                hitDoc = isearcher.doc(hits[i].doc);
                //  System.out.println(hitDoc.get("fieldname"));
                listOfSentences.add(hitDoc);
            }

How can I make this happen?

Is the word/string you are looking for in another string?
Do you have a definition for what characters delimit a word?
Regular expressions may do the job.

No idea if this makes any sense in the Lucene thread, which I just noticed.

Yes the word is in a String line which is indexed as Lucene Field.

So when I search the word for e.g house the results display me other fields where the word for e.g houses is. But I need only those fields where word house is.
