Class DrillSideways

Computes drill down and sideways counts for the provided DrillDownQuery. Drill sideways counts include alternative values/aggregates for the drill-down dimensions so that a dimension does not disappear after the user drills down into it.

Use one of the static search methods to do the search, and then get the hits and facet results from the returned DrillSidewaysResult.

NOTE: this allocates one FacetsCollector for each drill-down, plus one. If your index has high number of facet labels then this will multiply your memory usage. @lucene.experimental

Methods

Name Description
Dispose()
GetSurrogateId()
ScoreSubDocsAtOnce()

Override this and return true if your collector (e.g., ) expects all sub-scorers to be positioned on the document being collected. This will cause some performance loss; default is false. Note that if you return true from this method (in a subclass) be sure your collector also returns false from AcceptsDocsOutOfOrder: this will trick BooleanQuery into also scoring all subDocs at once.
