This package contains experimental classes to search over intervals within fields
IntervalsSourceclass can be used to construct proximity relationships between terms and intervals. They can be built using static methods in the
Intervals.term(String)— Represents a single term.
Intervals.phrase(java.lang.String...)— Represents a phrase.
Intervals.analyzedText(java.lang.String, org.apache.lucene.analysis.Analyzer, java.lang.String, int, boolean)— Represents a phrase (or an unordered sequence) of tokens resulting from an analysis of a given text.
Intervals.ordered(IntervalsSource...)— Represents an interval over an ordered set of terms or intervals.
Intervals.unordered(IntervalsSource...)— Represents an interval over an unordered set of terms or intervals.
Intervals.or(IntervalsSource...)— Represents the disjunction of a set of terms or intervals.
Intervals.wildcard(org.apache.lucene.util.BytesRef)— Represents an suffix wildcard (any prefix-matching term from the index).
Intervals.maxwidth(int, IntervalsSource)— Filters out intervals that are larger than a set width.
Intervals.maxgaps(int, IntervalsSource)— Filters out intervals that have more than a set number of gaps between their constituent sub-intervals.
Intervals.containedBy(IntervalsSource, IntervalsSource)— Returns intervals that are contained by another interval.
Intervals.notContainedBy(IntervalsSource, IntervalsSource)— Returns intervals that are *not* contained by another interval.
Intervals.containing(IntervalsSource, IntervalsSource)— Returns intervals that contain another interval.
Intervals.notContaining(IntervalsSource, IntervalsSource)— Returns intervals that do not contain another interval.
Intervals.nonOverlapping(IntervalsSource, IntervalsSource)— Returns intervals that do not overlap with another interval.
Intervals.notWithin(IntervalsSource, int, IntervalsSource)— Returns intervals that do not appear within a set number of positions of another interval.
Intervalsclass contains more advanced filters, please refer to the documentation of that class.
IntervalQuerytakes a field name and an
IntervalsSource, and matches all documents that contain intervals defined by the source in that field.
Interval query support in query parsers
StandardQueryParser (from the
queryparser module) supports interval
ClassDescriptionAn IntervalsSource that filters the intervals from another IntervalsSourceWraps an
IntervalIteratorand passes through those intervals that match the
DocIdSetIteratorthat also allows iteration over matching intervals in a document.An extension of MatchesIterator that allows it to be treated as an IntervalIteratorA query that retrieves documents containing intervals returned from an
IntervalsSourceFactory functions for creating
interval sources.A helper class for
IntervalQuerythat provides an
IntervalIteratorfor a given field and segment
