After getting my hand-written search working through curl I tried to  
start testing out the java version and I get this Exception when  
running my search:

org.codehaus.jackson.map.JsonMappingException: No serializer found for  
class org.elasticsearch.common.BytesHolder and no properties  
discovered to create BeanSerializer (to avoid exception, disable  
SerializationConfig.Feature.FAIL\_ON\_EMPTY\_BEANS) ) (through reference  
chain: org.elasticsearch.action.search.SearchResponse["hits"]-\>org.elasticsearch.search.internal.InternalSearchHits["hits"]-\>org.elasticsearch.search.internal.InternalSearchHit["sourceRef"])

googling around I haven't found anything on this specific one yet, so  
wanted to post here to see what might be going on. Anyone have some  
ideas? I'm running v.0.19.8.

After some investigation it looks like it might be caused by this  
entity in couchdb document coming across into ES:

"\_source" : {"tags":  
....  
}

I've seen some examples of how to configure the mapper in other  
projects, any suggestions on how to do this for ES?

Thanks!

You can use a script to modify your couchDb document before indexing it in ES.  
See couchDb river documentation.

I fixed all the documents that had weird tags and changed them to be  
"tags": null and I'm still getting the error. I've also tried a query  
that has every single field filled in on the document and I'm still  
getting that error so something else is going on :/.
