Issues in indexing or querying - search

Question

every one I m a beginner with Big Data and trying to index and search the data. I have a problem
1)- While indexing program runs very smoothly but while Searching It always shows one or zero hit per query.
Like this:-
Skipped write.lock

2 Documents Added.
Enter the Search Query (q=quit):
Waleed
Found 1 hits.
D:\Studies\Universities-Punjab University-\Notes\Final Year Project\Appache Lucene\Result 3\file.txt score=0.0390625
Enter the Search Query (q=quit):
Wlaeed
Found 0 hits.
Enter the Search Query (q=quit):
Ahmad
Found 1 hits.
D:\Studies\Universities-Punjab University-\Notes\Final Year Project\Appache Lucene\Result 3\file.txt score=0.0390625
Enter the Search Query (q=quit):
train
Found 1 hits.
D:\Studies\Universities-Punjab University-\Notes\Final Year Project\Appache Lucene\Result 3\lab 1.txt score=0.17900687
Enter the Search Query (q=quit):
q
Code for Indexing:-
Reader fr = null;
try {
Document doc = new Document();
fr = new FileReader(f);
doc.add(new StringField("path", f.getPath(), Field.Store.YES));
doc.add(new StringField("filename", f.getName(),Field.Store.YES));
doc.add(new TextField("contents", fr));
writer.addDocument(doc);
enhanceList(f, helper);
} catch (Exception e) {
System.out.println("Could Not Add: " + f);
} finally {
fr.close();
}
Code for Searching/Querying:-
void searching() throws IOException {
String s = "";
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
IndexReader reader = DirectoryReader.open(FSDirectory.open(new File(directory)));
IndexSearcher searcher = new IndexSearcher(reader);
while (!s.equalsIgnoreCase("q")) {
try {
System.out.println("Enter the Search Query (q=quit):");
s = br.readLine();
if (s.equalsIgnoreCase("q")) {
break;
}
Query q = new QueryParser(Version.LUCENE_44, "contents", analyzer).parse(s);
ScoreDoc[] hits = searcher.search(q, 1000).scoreDocs;
System.out.println("Found " + hits.length + " hits.");
for (int i = 0; i < hits.length; i++) {
int docId = hits[i].doc;
Document d = searcher.doc(docId);
System.out.println((i + 1) + ". " + d.get("path") + " score=" + hits[i].score);
}
} catch (Exception e) {
System.out.println("Error Searching " + s + " : " + e.getMessage());
}
}
}
Please any body help me out in finding out the solution..
