Thanks Arthur. I've seen the oslcTerms but I don't think it can behave as
a replacement of oslc.where with additional predicates. There are 2
reasons that make me say this:
- it seems it's possible for results that do not match the search terms to
be returned ( with oslc.score = 0) meaning that a larger set of data than
needed will be returned. Is my interpretation correct?
- the searchTerms performs sorting on the result set and it is defined to
override the oslc.sort parameter which might be not desirable in all
cases.

Re: [oslc-core] Enhancing OSLC Query filtering
Dragos,
There is a full text search mechanism. oslc.searchTerms [1]
The query syntax was intended to be simple and relatively easy to
implement. For complex queries, we should use a standard query language,
e.g. SPARQL. So rather than enhance the simple query syntax, we should be
promoting query based on SPARQL, e.g. from an index.

[oslc-core] Enhancing OSLC Query filtering
Sent by:

Hey all,
the oslc.where parameter of OSLC queries allow filtering data using basic
operators. In some cases this is not sufficient as expressing conditions
using basic operators is either not possible or very cumbersome. Can the
OSLC Query be enhanced with some common used predicates such as "like",
"contains" etc? An example is searching for all the resources that contain
a specific word in their dc:title property.

Dragos
