Functions

estimateDocCount

fun estimateDocCount(visitor: PointValues.IntersectVisitor): Long

Estimate the number of documents that would be matched by .intersect with the given IntersectVisitor. This should run many times faster than .intersect.

estimatePointCount

fun estimatePointCount(visitor: PointValues.IntersectVisitor): Long

Estimate the number of points that would be visited by .intersect with the given [ ]. This should run many times faster than .intersect.

fun intersect(visitor: PointValues.IntersectVisitor)

Finds all documents and points matching the provided visitor. This method does not enforce live documents, so it's up to the caller to test whether each document is deleted, if necessary.

open override fun size(): Long

Returns the total number of indexed points across all documents.
