I searched for "Content type", "content type", "Content_type" and "content_type" as I do not know whether it is case sensitive and nothing came out.

The point is that we have several resource providers from different backgrouns and we do not know exactly which fields are necessary for them to be included in the metadata, so we decided to give the freedom to them to define it. But it requires that we will be able to index them without already knowing their field names.

But it seems ithat something does not work on my ckan instance. If you say that I should be able to find the datasets which have "Content type" as their additinal field name.
