Class | Description |
---|---|
AnalysisOffsetStrategy |
Provides a base class for analysis based offset strategies to extend from.
|
DefaultPassageFormatter |
Creates a formatted snippet from the top passages.
|
FieldHighlighter |
Internal highlighter abstraction that operates on a per field basis.
|
FieldOffsetStrategy |
Ultimately returns a list of
OffsetsEnum yielding potentially highlightable words in the text. |
LengthGoalBreakIterator |
Wraps another
BreakIterator to skip past breaks that would result in passages that are too
short. |
MemoryIndexOffsetStrategy |
Uses an
Analyzer on content to get offsets and then populates a MemoryIndex . |
NoOpOffsetStrategy |
Never returns offsets.
|
OffsetsEnum |
Holds the term (
BytesRef ), PostingsEnum , offset iteration tracking. |
Passage |
Represents a passage (typically a sentence of the document).
|
PassageFormatter |
Creates a formatted snippet from the top passages.
|
PassageScorer |
Ranks passages found by
UnifiedHighlighter . |
PhraseHelper |
Helps the
FieldOffsetStrategy with strict position highlighting (e.g. |
PostingsOffsetStrategy |
Uses offsets in postings --
IndexOptions.DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS . |
PostingsWithTermVectorsOffsetStrategy |
Like
PostingsOffsetStrategy but also uses term vectors (only terms needed) for multi-term queries. |
SplittingBreakIterator |
Virtually slices the text on both sides of every occurrence of the specified character.
|
TermVectorOffsetStrategy |
Uses term vectors that contain offsets.
|
TokenStreamOffsetStrategy |
Analyzes the text, producing a single
OffsetsEnum wrapping the TokenStream filtered to terms
in the query, including wildcards. |
UnifiedHighlighter |
A Highlighter that can get offsets from either
postings (
IndexOptions.DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS ),
term vectors (FieldType.setStoreTermVectorOffsets(boolean) ),
or via re-analyzing text. |
UnifiedHighlighter.LimitedStoredFieldVisitor |
Fetches stored fields for highlighting.
|
Enum | Description |
---|---|
UnifiedHighlighter.HighlightFlag |
Flags for controlling highlighting behavior.
|
UnifiedHighlighter.OffsetSource |
Source of term offsets; essential for highlighting.
