----------------------------------------------------------------
after offline talk with [~chetanm] we have tweaked the proposal to have e.g. a
{{FacetResult}} class (living in _oak-core_) that will wrap the {{QueryResult}}
and will provide access to facets data via POJOs:
{code}
String sql2 = "select [jcr:path], [rep:facet(text)] from [nt:base] " +
"where contains([text], 'hello OR hallo') order by [jcr:path]";
Query q = qm.createQuery(sql2, Query.JCR_SQL2);
QueryResult queryResult = q.execute();
FacetResult facetResult = new FacetResult(queryResult);
String[] dimensions = facetResult.getDimensions(); // { "text" }
for (String dimension : dimensions) {
List<Facet> facets = facetResult.getFacets(dimension);
for (Facet facet : facets) {
System.out.println(facet.getLabel() + ":" + facet.getCount());
}
}
{code}
I'll follow up with a structured proposal for the {{FacetResult}} API.

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: lucene, solr
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Fix For: 1.3.14
>
>
> Current facet results are returned within the rep:facet($propertyname)
> property of each resulting node. The resulting String [1] is however a bit
> annoying to parse as it separates label / value by comma so that if label
> contains a similar pattern parsing may even be buggy.
> An easier format for facets should be used, eventually together with an
> utility class that returns proper objects that client code can consume.
