Hierarchical facet select a subtree but one child
Hi,
I'm a bit rusty with Lucene facets API and I have a common use case that
I would like to solve.
Suppose the following facet values tree:
Facet
- V1
- V1.1
- V1.2
- V1.3
- V1.4
- (not topK values)
- V2
- V2.1
- V2.2
- V2.3
- V2.4
- (not topK values)
With (not topK values) I mean values you are not showing in the UI
because of space/visualization problems. You usually see them with the
links "More ..."
Use case:
1 - select V1 => all V1.x are selected
2 - de-select V1.1
How can I achieve this? from the search results I know the values
V1.[1-4] but I don't know the values that are not in topK. How can I
select all the V1 subtree but V1.1?
Please let me know if you need more info.

Hi,
yes my aim was to introduce the functionality on the facet package.
I created a ticket and added a simple patch; the use case seems to apply
only to hierarchical facets, maybe we can add a validation to avoid to
use the method in other cases.
I'm happy to make modifications to the patch if you have any comment.

I think this is a missing API in DrillDownQuery?
Nicola, could you open an issue?
The filtering is as Mike Sokolov described, but I think we should add a
sugar method, e.g. DrillDownQuery.remove or something, to add a negated
query clause.
And until this API is added and you can upgrade to it, you can construct
your own TermQuery and then add it as a MUST_NOT clause. Look at how
DrillDownQuery.add converts incoming facet paths to terms and use that
public DrillDownQuery.term method it exposes to create your own negated
TermQuery.

Re: Hierarchical facet select a subtree but one child

If you are trying to show documents that have facet value V1 excluding
those with facet value V1.1, then you would need to issue a query
like:
+f:V1 -f:V1.1
assuming your facet values are indexed in a field called "f". I don't
think this really has anything to do with faceting; it's just a
filtering problem.

Hi,
is there someone that can point me in the right API to negate facet
values?
May be this DrillDownQuery#add(dim, query) the API to permit this use
case?
