Description

Apache Olingo project (http://olingo.incubator.apache.org/) provides implementation for OData (http://odata.org/).

This task is about adapting OLingo URI Parser to CXF Search API.
org.apache.cxf.jaxrs.ext.search.SearchConditionParser implementation will use Olingo parser. The existing CXF Search visitors will be expected to work with both FIQL and OData parsers.

We may hit some limitations in the existing CXF Search API because OData is more sophisticated language than FIQL.

At the moment I don't think it is realistic to support OData completely within CXF Search API constraints. Most likely we will just settle for supporting the subset of OData queries, with users being recommended to work directly with Olingo to get a complete support. Alternatively we can try and enhance the search API if it proves feasible.
