Hi, I have a document in an index, with the following array indexed (I've verified that this is what it looks in the index): tag\_ids: [2, 4, 5, 63, 15] I retrieve this document via a prepareGet(): GetResponse r = SearchClient.instance().prepareGet(...).setFields(...).execute().actionGet(); The problem occurs when I try to access the tag\_ids field: tags = (List) r.field("tag\_ids").getValue(); This results in the following error: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.util.List I've added the following log statement: Logger.info("CLASS: " + r.field("tag\_ids").getValue().getClass().getName() - ", value: " + r.field("tag\_ids").getValue()); Which results in: CLASS: java.lang.Integer, value: 19 I don't really understand this behaviour. The value 19 is not even in the array? What am I doing wrong here? I've then tried changing from getValue() to getValues(): tags = r.field("tag\_ids").getValues(); This then works fine. HOWEVER, after one or more re-indexing rounds of the document (without changing the contents of tag\_ids field), the following error occurs when accessing the field: java.lang.NumberFormatException: For input string: "[2, 4, 5, 63, 15]" This occurs when performing Long.parseLong(o.toString()) where o is an object in the array. So now the first object in the List retrieved via getValues() is a String representation of the int array? I then restart the ElasticSearch server, and the problem goes away for this document. But as soon as it is re-indexed, the problem reoccurs. What am I doing wrong here? What is the correct way of accessing the array from the GetResponse, to get consistent results? Thanks for your help! Best regards, OGG -- ---

This problem seems to go away if I do a flush after indexing the data: client.admin().indices().prepareFlush().execute().actionGet(); Is that necessary?

Necessary if you are performing your search immediatly after your doc insert (unit test). But, don't do it in production. Elasticsearch is a "Near Real Time" search engine. ## HTH David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 3 oct. 2012 à 16:39, Ólafur Gauti Guðmundsson [oli.gauti@gmail.com](mailto:oli.gauti@gmail.com) a écrit : > This problem seems to go away if I do a flush after indexing the data: > > client.admin().indices().prepareFlush().execute().actionGet(); > > Is that necessary? > > Thanks, > OGG > > On Tuesday, September 11, 2012 1:13:57 PM UTC, Ólafur Gauti Guðmundsson wrote: > Hi, > I have a document in an index, with the following array indexed (I've verified that this is what it looks in the index): > > tag\_ids: [2, 4, 5, 63, 15] > > I retrieve this document via a prepareGet(): > > GetResponse r = SearchClient.instance().prepareGet(...).setFields(...).execute().actionGet(); > > The problem occurs when I try to access the tag\_ids field: > > tags = (List) r.field("tag\_ids").getValue(); > > This results in the following error: > > java.lang.ClassCastException: java.lang.Integer cannot be cast to java.util.List > > I've added the following log statement: > > Logger.info("CLASS: " + r.field("tag\_ids").getValue().getClass().getName() + ", value: " + r.field("tag\_ids").getValue()); > > Which results in: > > CLASS: java.lang.Integer, value: 19 > > I don't really understand this behaviour.

Its not necessary. Might be you need to refresh, but with "get" there isn't a need to do that as well. Can you possibly gist a simple test cast of this happening? One more question, do you have special mapping for tag\_ids, marking it as stored perhaps?

Thanks for the reply! Yes, the tag\_ids field is marked as stored in my mapping: "tag\_ids" : {"store" : "yes", "type":"integer", "index" : "not\_analyzed"} I'll try to create a simple case demonstrating this.
