The ability to execute complete graph queries over arbitrarily complex graphs of indexed tokens opens a number of new possibilities
Overview of a candidate implementation providing complete, performant, configurable graph query support over indexed token graphs in Lucene.
SpanNearQuery is arguably the essential component of graph queries in Lucene. Over time, enhancements to various Lucene components have increasingly invalidated some fundamental assumptions in the
SpanNearQuery graph query implementation, leading to buggy and/or unpredictable query behavior.
