Hi,

I am using CouchDB as main DB with Elasticsearch (using River CouchDB  
plugin) for fulltext search.

I have a database called "apps" where I have a list of mobile  
applications.

I have created a filter that basically only hits documents that has  
doc.type=="app"

When doing a curl:

curl [http://localhost:5984/apps/\_changes?filter=replication/apps](http://localhost:5984/apps/_changes?filter=replication/apps)

It seems to work fine, 50 apps is returned.

I have then setup Elasticsearch to use the database "apps" and the  
filter "replication/apps"

But in Elasticsearch, I only get 7 "apps", not 50.

Another problem seems to be that Elasticsearch cannot handle nested  
objects correctly.

eg. Many of the mobile applications have screenshots like $doc-

> screenshot[0]-\>type = 'png'

When watching the documents in Elasticsearch, it seems like that neep  
nested "type" has overridden the $doc-\>type and show it as "png"  
instead of "app".

Does anyone have experience with any of this?

Regards,  
Daniele

Hi Daniele,

I use CouchDB River in production and have not seen this issue.

Would it be possible for you to share your 'filter' and a sample doc  
which is getting  
indexed ?

Also, can you turn on debug logs in Elasticsearch (conf/logging.yml)  
and then setup the  
river plugin again. The debug outputs may give some hints on what is  
going wrong.

Regards,  
Mahendra
