allow searching by type

We have a use case where we upload various types of content in zip files into our artifact server - and we use type of the artifact to denote what is contained in the zip file.

For example:

<dependency>
<groupId>foo</groupId>
<artifactId>bar</artifactId>
<version>1.0</version>
<type>ibdf.zip</type>
</dependency>

We use the classifier for other purposes.

I don't see a way to do a lucene query on 'type'. You have packaging - but packaging != type - our packaging type is pom, for example.

Is there any way to construct a query (and utilize the rest interface) to get back a list of all artifacts of a particular type?

It also seems that you cannot enter a query with just the packaging? I get no results if I just search for pom, or jar packaging, for example. If support was added for indexing type - it would need to be usable by itself, for my use case.

I'm fairly familiar with lucene - if someone could point me at the right source code, I could probably come up with a patch (assuming I'm not being dense if the feature already exists)
