Class DocValuesNumbersQuery

java.lang.Object
org.apache.lucene.search.Query
org.apache.lucene.sandbox.search.DocValuesNumbersQuery
All Implemented Interfaces:
Accountable

public class DocValuesNumbersQuery extends Query implements Accountable
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.

NOTE: be very careful using this query: it is typically much slower than using TermsQuery, but in certain specialized cases may be faster.

  • Method Details

    • equals

      public boolean equals(Object other)
      Description copied from class: Query
      Override and implement query instance equivalence properly in a subclass. This is required so that QueryCache works properly.

      Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical that other instance. Utility methods are provided for certain repetitive code.

      Specified by:
      equals in class Query
      See Also:
    • equalsTo

      private boolean equalsTo(DocValuesNumbersQuery other)
    • hashCode

      public int hashCode()
      Description copied from class: Query
      Override and implement query hash code properly in a subclass. This is required so that QueryCache works properly.
      Specified by:
      hashCode in class Query
      See Also:
    • visit

      public void visit(QueryVisitor visitor)
      Description copied from class: Query
      Recurse through the query tree, visiting any child queries
      Specified by:
      visit in class Query
      Parameters:
      visitor - a QueryVisitor to be called by each query in the tree
    • getField

      public String getField()
    • getNumbers

      public Set<Long> getNumbers()
    • toString

      public String toString(String defaultField)
      Description copied from class: Query
      Prints a query to a string, with field assumed to be the default field and omitted.
      Specified by:
      toString in class Query
    • ramBytesUsed

      public long ramBytesUsed()
      Description copied from interface: Accountable
      Return the memory usage of this object in bytes. Negative values are illegal.
      Specified by:
      ramBytesUsed in interface Accountable
    • createWeight

      public Weight createWeight(IndexSearcher searcher, ScoreMode scoreMode, float boost) throws IOException
      Description copied from class: Query
      Expert: Constructs an appropriate Weight implementation for this query.

      Only implemented by primitive queries, which re-write to themselves.

      Overrides:
      createWeight in class Query
      scoreMode - How the produced scorers will be consumed.
      boost - The boost that is propagated by the parent queries.
      Throws:
      IOException
