https://open-services.net/bin/view/Main/OSLCCoreSpecQuery describes two differenty types of query:
1) A text search query specified by oslc.searchTerms
2) A property graph based query specified by oslc.where
In order to ease the implementation buden of the spec, we should allow servers to implement one but not necessarily both. Currently a client has no means of discovering whether either or both are supported before issuing a query request.
The spec should define the behaviour if oslc.searchTerms or oslc.where is specified but the server does not support that capability.
