The calculus of spans.

org.apache.lucene.util |
Some utility classes.
|
Modifier and Type | Class and Description |
---|---|
class |
FieldMaskingSpanQuery
Wrapper to allow
SpanQuery objects participate in composite
single-field SpanQueries by 'lying' about their search field. |
class |
SpanBoostQuery
Counterpart of
BoostQuery for spans. |
class |
SpanContainingQuery
Keep matches that contain another SpanScorer.
|
class |
SpanFirstQuery
Matches spans near the beginning of a field.
|
class |
SpanMultiTermQueryWrapper<Q extends MultiTermQuery>
Wraps any
MultiTermQuery as a SpanQuery ,
so it can be nested within other SpanQuery classes. |
class |
SpanNearQuery
Matches spans which are near one another.
|
class |
SpanNotQuery
Removes matches which overlap with another SpanQuery or which are
within x tokens before or y tokens after another SpanQuery.
|
class |
SpanOrQuery
Matches the union of its clauses.
|
class |
SpanPositionCheckQuery
Base class for filtering a SpanQuery based on the position of a match.
|
class |
SpanPositionRangeQuery
Checks to see if the
SpanPositionCheckQuery.getMatch() lies between a start and end position
See SpanFirstQuery for a derivation that is optimized for the case where start position is 0. |
class |
SpanTermQuery
Matches spans containing a term.
|
class |
SpanWithinQuery
Keep matches that are contained within another Spans.
