> I am trying out jackrabbit oak with lucene in a file node store. The index definition record is created successfully but it seems the index record is not created. lucene index creation code snippets:
>  
> {code:java}
> public void initRepository() {
>  LuceneIndexProvider provider = new LuceneIndexProvider();
>  Jcr jcr = new Jcr(nodeStore)
>  .withAsyncIndexing("async",3)
>  .with(new LuceneIndexEditorProvider())
>  .with((QueryIndexProvider) provider)
>  .with((Observer) provider)
>  .withAsyncIndexing("async",3);
>  repository = jcr.createRepository();
>  log.info("Repository initialized");
>  }
> public void createLuceneIndex() throws RepositoryException {
>  Session session = createAdminSession();
>  Node lucene = JcrUtils.getOrCreateByPath("/oak:index/lucene", "oak:Unstructured",
>  "oak:QueryIndexDefinition", session, false);
>  lucene.setProperty("compatVersion", 2);
>  lucene.setProperty("type", "lucene");
>  lucene.setProperty("async", "async");
>  Node rules = lucene.addNode("indexRules", "nt:unstructured");
>  Node allProps = rules.addNode("nt:base")
>  .addNode("properties", "nt:unstructured")
>  .addNode("allProps", "oak:Unstructured");
>  allProps.setProperty(Property.JCR_DATA, ".*");
>  allProps.setProperty("isRegexp", true);
>  allProps.setProperty("nodeScopeIndex", true);
>  session.save();
>  session.logout();
>  log.info("Lucene index created");
>  }
> {code}
>  
> After creating Lucene index, I have uploaded *test.doc* file in node store using below code:
>  
> {code:java}
> log.info("Setting the JCR content for file name: test.doc, under path: " + folderNode.getPath());
> final Binary binary = new BinaryImpl(fileBytes);
> final Node content = folderNode.addNode(Property.JCR_CONTENT, NodeType.NT_RESOURCE);
> content.setProperty(Property.JCR_DATA, binary);
> //JCR session save code here
> {code}
>  
> test.doc file contents:
> {code:java}
> HelloWorld, Test file contents for Full text search using Lucene index.{code}
>  
> I have used below query to fetch result:
>  
> {code:java}
> final Query query = queryManager.createQuery(
>          "select * from [nt:base] where contains(*, 'HelloWorld')",
>          Query.JCR_SQL2);
> final QueryResult result = query.execute();
> final NodeIterator nodeIter = result.getNodes();
> log.info("Number of nodes: " + nodeIter.getSize());{code}
> But this query is not returning node where file contents are stored. I am getting below result:
> {code:java}
> Number of nodes: 0{code}
> Logs:
> {code:java}
> "Traversal query (query without index): select * from [nt:base] where contains(*,'HelloWorld'); consider creating an index"{code}
> Could you please let me know where I am making mistake or how to create proper index and do full text search on binary contents.
