ClassDescriptionA
Query
that treats multiple fields as a single stream and scores terms as if you had indexed them as a single term in a single field.A builder forCombinedFieldQuery
.AQuery
that allows to have a configurable number or required matches per document.AScorer
whose number of matches is per-document.AQuery
that only accepts documents whose term value in the specified field is contained in the provided set of allowed terms.Optimized collector for large number of hits.Holder class for prototype sandboxed queriesCopy ofLeafSimScorer
that sums document's norms from multiple fields.Abstract class for range queries involving multiple ranges against physical points such asIntPoints
All ranges are logically ORed togetherA builder for multirange queries.A range represents anything with a min/max value that can compute its relation with another range and can compute if a point is inside itRepresentation of a single clause in a MultiRangeQueryAn interval tree of Ranges for speeding up computationsRepresents a range that can compute its relation with another range and can compute if a point is inside itKNN search on top of 2D lat/lon indexed points.A generalized version ofPhraseQuery
, built with one or moreMultiTermQuery
that provides term expansions for multi-terms (one of the expanded terms must match).Builds aPhraseWildcardQuery
.Phrase term with expansions.AllPhraseWildcardQuery.PhraseTerm
are light and immutable.Phrase term with no expansion.Holds a pair of term bytes - term state.Holds theTermState
andTermStatistics
for all the matched and collectedTerm
, for all phrase terms, for all segments.Accumulates the doc freq and total term freq.Test counters incremented when assertions are enabled.This class wraps a Collector and times the execution of: - setScorer() - collect() - doSetNextReader() - needsScores()Public class for profiled timings of the Collectors used in the search.A collector that profiles how much time is spent calling it.A record of timings for the various operations that may happen during query execution.An extension ofIndexSearcher
that records profile information for all queries it executes.This class is the internal representation of a profiled Query, corresponding to a single node in the query tree.Scorer
wrapper that will compute how much time is spent on moving the iterator, confirming matches and computing scores.Helps measure how much time is spent running some methods.This enum breaks down the query into different sections to describe what was timed.This class tracks the dependency tree for queries (scoring and rewriting) and generatesQueryProfilerBreakdown
for each node in the tree.A proximity query that lets you express an automaton, whose transitions are terms, to match documents.Sorts by docID so we can quickly pull out all scorers that are on the same (lowest) docID.Sorts by position so we can visit all scorers on one doc, by position.Consumes a TokenStream and creates anTermAutomatonQuery
where the transition labels are tokens from theTermToBytesRefAttribute
