Interface  Description 

IntervalMatchesIterator 
An extension of MatchesIterator that allows it to be treated as
an IntervalIterator
This is necessary to get access to
IntervalIterator.gaps()
and IntervalIterator.width() when constructing matches 
Class  Description 

FilteredIntervalsSource 
An IntervalsSource that filters the intervals from another IntervalsSource

IntervalFilter 
Wraps an
IntervalIterator and passes through those intervals that match the IntervalFilter.accept() function 
IntervalIterator 
A
DocIdSetIterator that also allows iteration over matching
intervals in a document. 
IntervalQuery 
A query that retrieves documents containing intervals returned from an
IntervalsSource
Static constructor functions for various different sources can be found in the
Intervals class
Scores for this query are computed as a function of the sloppy frequency of
intervals appearing in a particular document. 
Intervals 
Constructor functions for
IntervalsSource types
These sources implement minimuminterval algorithms taken from the paper
Efficient Optimally Lazy Algorithms for MinimalInterval Semantics
By default, sources that are sensitive to internal gaps (e.g. 
IntervalsSource 
A helper class for
IntervalQuery that provides an IntervalIterator
for a given field and segment
Static constructor functions for various different sources can be found in the
Intervals class 
IntervalsSource
class can be used to construct proximity
relationships between terms and intervals. They can be built using static methods
in the Intervals
class
Intervals.term(String)
— Represents a single termIntervals.phrase(java.lang.String...)
— Represents a phraseIntervals.ordered(IntervalsSource...)
— Represents an interval over an ordered set of terms or intervalsIntervals.unordered(IntervalsSource...)
— Represents an interval over an unordered set of terms or intervalsIntervals.or(IntervalsSource...)
— Represents the disjunction of a set of terms or intervalsIntervals.maxwidth(int, IntervalsSource)
— Filters out intervals that are larger than a set widthIntervals.maxgaps(int, IntervalsSource)
— Filters out intervals that have more than a set number of gaps between their constituent subintervalsIntervals.containedBy(IntervalsSource, IntervalsSource)
— Returns intervals that are contained by another intervalIntervals.notContainedBy(IntervalsSource, IntervalsSource)
— Returns intervals that are *not* contained by another intervalIntervals.containing(IntervalsSource, IntervalsSource)
— Returns intervals that contain another intervalIntervals.notContaining(IntervalsSource, IntervalsSource)
— Returns intervals that do not contain another intervalIntervals.nonOverlapping(IntervalsSource, IntervalsSource)
— Returns intervals that do not overlap with another intervalIntervals.notWithin(IntervalsSource, int, IntervalsSource)
— Returns intervals that do not appear within a set number of positions of another intervalIntervalQuery
takes a field name and an IntervalsSource
,
and matches all documents that contain intervals defined by the source in that field.Copyright © 20002021 Apache Software Foundation. All Rights Reserved.
