Searching Using Solr Query Language

Hello,

The company i work for has recently switched to Windchill 10.0 and I have discovered the advanced search option using solr query language syntax in the keyword field. I have never used solr before and was wondering if there was an easy way to determine the searchable fields. As of now, i have only found two; name: and number:

Searching other fields such as version or context give a bad request error.

Thanks!
