You should be able to get the textual field values by explicitly requesting them from fields.

It looks like that indexing code might not be correct. I just tried this code and it works for me: ``` try { String fileContents = readContent( new File( "fn6742.pdf" ) ); try { DeleteIndexResponse deleteIndexResponse = new ``` DeleteIndexRequestBuilder( client.admin().indices(), INDEX\_NAME ).execute().actionGet(); if (deleteIndexResponse.isAcknowledged() ) { System.out.println( "Deleted index" ); } } catch (Exception e) { //ignore } ``` CreateIndexResponse createIndexResponse = new ``` CreateIndexRequestBuilder( client.admin().indices(), INDEX\_NAME ).execute().actionGet(); ``` if ( createIndexResponse.isAcknowledged() ) { System.out.println( "Created index" ); } PutMappingResponse putMappingResponse = new ``` PutMappingRequestBuilder( client.admin().indices() ).setIndices(INDEX\_NAME).setType( DOCUMENT\_TYPE ).setSource( XContentFactory.jsonBuilder().startObject() .field("doc").startObject() .field( "properties" ).startObject() .field( "file" ).startObject() .field( "term\_vector", "with\_positions\_offsets" ) .field( "store", "yes" ) .field( "type", "attachment" ) .field("fields").startObject() .field("file").startObject() .field("store", "yes") .endObject() .endObject() .endObject() .endObject() .endObject() .endObject() ).execute().actionGet(); ``` if ( putMappingResponse.isAcknowledged() ) { System.out.println( "Successfully defined mapping" ); } IndexResponse indexResponse = client.prepareIndex( INDEX_NAME , ``` DOCUMENT\_TYPE, "1") .setSource(XContentFactory.jsonBuilder() .startObject() .field( "file").startObject() .field("content", fileContents) .field("\_indexed\_chars", -1) .endObject() .endObject() ).execute().actionGet(); ``` System.out.println( "Document indexed success: " + ``` indexResponse.isCreated() ); } catch ( Exception e ) { System.out.println(e.toString()); } And then when I query: { "fields": "\*", "query": { "match\_all": {} } } I get back this: { "took" : 2, "timed\_out" : false, "\_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 1, "max\_score" : 1.0, "hits" : [ { "\_index" : "msdocs", "\_type" : "doc", "\_id" : "1", "\_score" : 1.0, "fields" : { "file" : [ "\n1\nISL99201\nCAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.\n1-888-INTERSIL or 1-888-468-3774"] } } ] } } -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You are correct, my JSON mapping had a wrong entry. Thanks for the help! On Friday, February 7, 2014 6:10:50 PM UTC-5, Binh Ly wrote: > It looks like that indexing code might not be correct.
