-------------------------------------
Summary: Add IntervalQuery and IntervalsSource to expose minimum
interval semantics across term fields
Key: LUCENE-8196
URL: https://issues.apache.org/jira/browse/LUCENE-8196
Project: Lucene - Core
Issue Type: New Feature
Reporter: Alan Woodward
Assignee: Alan Woodward
Attachments: LUCENE-8196.patch
This ticket proposes an alternative implementation of the SpanQuery family that
uses minimum-interval semantics from
[http://vigna.di.unimi.it/ftp/papers/EfficientAlgorithmsMinimalIntervalSemantics.pdf]
to implement positional queries across term-based fields. Rather than using
TermQueries to construct the interval operators, as in LUCENE-2878 or the
current Spans implementation, we instead use a new IntervalsSource object,
which will produce IntervalIterators over a particular segment and field.
These are constructed using various static helper methods, and can then be
passed to a new IntervalQuery which will return documents that contain one or
more intervals so defined.
