public class PostingsOffsetStrategy
extends FieldOffsetStrategy

Uses offsets in postings -- IndexOptions.DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS. This does not support multi-term queries; the highlighter will fallback on analysis for that.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
