DefaultPassageFormatter

Creates a formatted snippet from the top passages.

The default implementation marks the query terms as bold, and places ellipses between unconnected passages.

ICUPostingsHighlighter

Simple highlighter that does not analyze fields nor use term vectors. Instead it requires DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS.

Passage

Represents a passage (typically a sentence of the document).

A passage contains NumMatches highlights from the query, and the offsets and query terms that correspond with each match.
