Hi, I am just trying to do a simple search and retrieve the source document but it looks like its having troubles finding a lucene class, is there anything I am missing or doing wrong or is this a bug? Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/document/FieldSelector at org.elasticsearch.search.internal.InternalSearchHit.sourceAsMap(InternalSearchHit.java:239) at org.elasticsearch.search.internal.InternalSearchHit.getSource(InternalSearchHit.java:208) at test.Main.main(Main.java:42) Caused by: java.lang.ClassNotFoundException: org.apache.lucene.document.FieldSelector ``` Client client = new TransportClient() .addTransportAddress(new ``` InetSocketTransportAddress("host\_name", 9300)); ``` TextQueryBuilder tqb1 = new TextQueryBuilder("pages.pageText", ``` "text\_to\_find") .type(TextQueryBuilder.Type.PHRASE); ``` SearchResponse response = client.prepareSearch("index_name") .setSearchType(SearchType.QUERY_AND_FETCH) .setQuery(tqb1) .execute() .actionGet(); for (SearchHit hit : response.getHits()){ Map source = hit.getSource(); } ``` ---

Bad classpath. Are you mixing Elasticsearch with Lucene dependencies ? Check your project dependencies.

OK, was originally elasticsearch-0.19.8.jar went back to using elasticsearch-0.19.0.jar and it started working fine...

ES 0.19.8 uses Lucene 3.6, while ES 0.19.0 uses Lucene 3.5, which means you probably had Lucene 3.5 in your classpath while using 0.19.8.
