Hi,
I'm just getting started with Lucene for e-commerce. Thanks to awesome blog
posts from Shai and Mike, I'm up and running with drill sideways, faceting
and single pass grouping, but am unsure how to smooth a few things out
around faceting and grouping.
Here's what I'm stuck on:
1. With block grouping, how do I get facets with values / counts for each
dimension where the count uses my grouping?
I was able to use TermGroupFacetCollector when I used two pass grouping,
but I don't see how to do this with block groups / single pass. Even with
TermGroupFacetCollector, I wasn't sure how to get group counts when I
wasn't using SortedSetDocValues on a given field.
2. Drill sideways with dynamic range faceting
Can I use dynamic range faceting with drill sideways? I'm trying to use
LongRangeFacetCounts, with a FacetsCollector but, when I run query that has
the following
drillDownQuery.add("lowestPriceCents",
NumericRangeQuery.newIntRange("lowestPriceCents", 500, 1000, true, true))
then I do something like
val facetsCollector = new FacetsCollector
searcher.search(query, facetsCollector)
new LongRangeFacetCounts("price", facetsCollector, Array(
new LongRange("<5", 0, true, 5 * 100, false),
new LongRange("5-10", 5 * 100, true, 10 * 100, false),
new LongRange("10-50", 10 * 100, true, 50 * 100, false),
new LongRange(">50", 50 * 100, true, Long.MaxValue, false)
): _*)
However, I just get facets as if I'm drilling down. Can I use
LongRangeFacetCounts with drill sideways to get counts for all ranges?
3. For multi valued facet dimensions, I'm getting a value / count of -1.
For a dimension where I set multivalued to true:
facetsConfig.setMultiValued("photoOrientation", true)
I noticed that I get -1 as the value / count for the whole dimension.
Is this expected? How do I get the actual count? In some sense, maybe this
doesn't quite matter how I have it now, because I actually want grouped
facet counts and not the non-grouped facet counts.
Any help or pointers is really appreciated!
Thanks,
Jon
