Problems with ElasticSearch

[Daniele Testa <da...@gmail.com>]

Hi,

This might be more of a ElasticSearch question, but someone might be
able to help me anyways.

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

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

you can explicitly define mappings.
Usually, mappings from document properties to search fields are
implicit, but I think it's possible to override them.
You should direct your question to the elasticsearch community:
