I have noticed inconsistent behaviour when using the

(collection: collection_name)

modifier to force mongoid to read from / write to a different collection.

First of all this doesn't work as expected:

Search.with(collection: "search_collection_1").where(...)

doesn't work. Instead you need to add

 to make it work, like:

ruby
Search.all.with(collection: "search_collection_1").where(...)

Furthermore, when I create a new object with 

with

 then consequent updates to the object use the correct collection, i.e:

ruby
search = Search.with(collection: "search_collection_1").create(id: "xyz", data1: "some useful data...")
search.inc(usage: 1) # this will update the document in the correct collection

However during retrieval this is not the case:

ruby
search = Search.with(collection: "search_collection_1").where(id: "xyz").first
search.inc(usage: 1) # this will update the document in the default "searches" collection (practically it will do nothing, since the document is not there)

search.with(collection: "search_collection_1")
search.inc(usage: 2) # now it use the proper collection
`

Is this something that will be fixed?
Or is it supposed to work like this?
