Explaining faceting and the non trivial way to read and select facets is not easy. We chould could simplify things by renaming a few APIs around canonical concepts:
- FacetingRequest
- Facet group
- Facet selection
- Facet
Possible renames are:
- FullTextQuery.enableFaceting -> FullTextQuery.enableFacetingRequest
- FullTextQuery.disableFaceting -> FullTextQuery.disableFacetingRequest
- FacetManager.getFacets() -> FacetManager.getFacetGroup()
- FacetManager.getFacetGroup() -> FacetManager.getFacetSelection()
{code}
FacetingRequest categoryFaceting = qb.facet()
.name("category")
.onField("event.category.description")
.discrete()
.includeZeroCounts(true)
.orderedBy(FacetSortOrder.FIELD_VALUE)
.createFacetingRequest();
objectQuery.getFacetManager().enableFacetingRequest(categoryFaceting);
...
FacetManager fm = objectQuery.getFacetManager();
Facet selectedFacet = fm.getFacetGroup("category").get(categoryFacetId);
fm.getFacetSelection("category").selectFacets(selectedFacet);
{code}
This is more an example to get us talk on the subject than a fully fledged proposal but since we do break things in 5, it's a good time to start it.
