Package org.apache.lucene.sandbox.search

This package contains a flexible graph-based proximity query, TermAutomatonQuery, and geospatial queries.

Interface Summary

Interface	Description
IndexSortSortedNumericDocValuesRangeQuery.ValueComparator	Compares the given document's value with a stored reference value.
MultiRangeQuery.Range	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 it
MultiRangeQuery.Relatable	Represents a range that can compute its relation with another range and can compute if a point is inside it

Class Summary

Class	Description
CombinedFieldQuery	A 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.
CombinedFieldQuery.Builder	A builder for CombinedFieldQuery.
CombinedFieldQuery.CombinedFieldScorer
CombinedFieldQuery.FieldAndWeight
CombinedFieldQuery.WeightedDisiWrapper
CoveringQuery	A Query that allows to have a configurable number or required matches per document.
CoveringQuery.CoveringWeight
CoveringScorer	A Scorer whose number of matches is per-document.
DocValuesNumbersQuery	Like DocValuesTermsQuery, but this query only runs on a long NumericDocValuesField or a SortedNumericDocValuesField, matching all documents whose value in the specified field is contained in the provided set of long values.
DocValuesTermsQuery	A Query that only accepts documents whose term value in the specified field is contained in the provided set of allowed terms.
IndexSortSortedNumericDocValuesRangeQuery	A range query that can take advantage of the fact that the index is sorted to speed up execution.
IndexSortSortedNumericDocValuesRangeQuery.BoundedDocIdSetIterator	A doc ID set iterator that wraps a delegate iterator and only returns doc IDs in the range [firstDocInclusive, lastDoc).
LargeNumHitsTopDocsCollector	Optimized collector for large number of hits.
LatLonPointPrototypeQueries	Holder class for prototype sandboxed queries
LongHashSet
MultiNormsLeafSimScorer	Copy of LeafSimScorer that sums document's norms from multiple fields.
MultiNormsLeafSimScorer.MultiFieldNormValues
MultiRangeQuery	Abstract class for range queries involving multiple ranges against physical points such as IntPoints All ranges are logically ORed together
MultiRangeQuery.Builder	A builder for multirange queries.
MultiRangeQuery.RangeClause	Representation of a single clause in a MultiRangeQuery
MultiRangeQuery.RangeTree	An interval tree of Ranges for speeding up computations
NearestNeighbor	KNN search on top of 2D lat/lon indexed points.
NearestNeighbor.Cell
NearestNeighbor.NearestHit	Holds one hit from NearestNeighbor.nearest(double, double, java.util.List<org.apache.lucene.index.PointValues>, java.util.List<org.apache.lucene.util.Bits>, java.util.List<java.lang.Integer>, int)
NearestNeighbor.NearestVisitor
PhraseWildcardQuery	A generalized version of PhraseQuery, built with one or more MultiTermQuery that provides term expansions for multi-terms (one of the expanded terms must match).
PhraseWildcardQuery.Builder	Builds a PhraseWildcardQuery.
PhraseWildcardQuery.MultiTerm	Phrase term with expansions.
PhraseWildcardQuery.PhraseTerm	All PhraseWildcardQuery.PhraseTerm are light and immutable.
PhraseWildcardQuery.SingleTerm	Phrase term with no expansion.
PhraseWildcardQuery.TermBytesTermState	Holds a pair of term bytes - term state.
PhraseWildcardQuery.TermData	Holds the TermState for all the collected Term, for a specific phrase term, for all segments.
PhraseWildcardQuery.TermsData	Holds the TermState and TermStatistics for all the matched and collected Term, for all phrase terms, for all segments.
PhraseWildcardQuery.TermStats	Accumulates the doc freq and total term freq.
PhraseWildcardQuery.TestCounters	Test counters incremented when assertions are enabled.
ProfilerCollector	This class wraps a Collector and times the execution of: - setScorer() - collect() - doSetNextReader() - needsScores()
ProfilerCollectorResult	Public class for profiled timings of the Collectors used in the search.
ProfilerCollectorWrapper	A collector that profiles how much time is spent calling it.
QueryProfilerBreakdown	A record of timings for the various operations that may happen during query execution.
QueryProfilerIndexSearcher	An extension of IndexSearcher that records profile information for all queries it executes.
QueryProfilerResult	This class is the internal representation of a profiled Query, corresponding to a single node in the query tree.
QueryProfilerScorer	Scorer wrapper that will compute how much time is spent on moving the iterator, confirming matches and computing scores.
QueryProfilerTimer	Helps measure how much time is spent running some methods.
QueryProfilerTree	This class tracks the dependency tree for queries (scoring and rewriting) and generates QueryProfilerBreakdown for each node in the tree.
QueryProfilerWeight	Weight wrapper that will compute how much time it takes to build the Scorer and then return a Scorer that is wrapped in order to compute timings as well.
TermAutomatonQuery	A proximity query that lets you express an automaton, whose transitions are terms, to match documents.
TermAutomatonQuery.EnumAndScorer
TermAutomatonScorer
TermAutomatonScorer.DocIDQueue	Sorts by docID so we can quickly pull out all scorers that are on the same (lowest) docID.
TermAutomatonScorer.PositionQueue	Sorts by position so we can visit all scorers on one doc, by position.
TermAutomatonScorer.PosState
TermAutomatonScorer.TermRunAutomaton
TokenStreamToTermAutomatonQuery	Consumes a TokenStream and creates an TermAutomatonQuery where the transition labels are tokens from the TermToBytesRefAttribute.

Enum Summary

Enum	Description
QueryProfilerTimingType	This enum breaks down the query into different sections to describe what was timed.
