Enclosing class:
AbstractKnnVectorQuery

static class AbstractKnnVectorQuery.DocAndScoreQuery extends Query
Caches the results of a KnnVector search: a list of docs and their scores

      DocAndScoreQuery(int[] docs, float[] scores, float maxScore, int[] segmentStarts, Object contextIdentity)
      Constructor
      Parameters:
      docs - the global docids of documents that match, in ascending order
      scores - the scores of the matching documents
      segmentStarts - the indexes in docs and scores corresponding to the first matching document in each segment. If a segment has no matching documents, it should be assigned the index of the next segment that does. There should be a final entry that is always docs.length-1.
      contextIdentity - an object identifying the reader context that was used to build this query
  • Method Details

    • 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
      Parameters:
      scoreMode - How the produced scorers will be consumed.
      boost - The boost that is propagated by the parent queries.
      Throws:
      IOException
    • toString

      public String toString(String field)
      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
    • 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
    • equals

      public boolean equals(Object obj)
      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 to those of the other instance. Utility methods are provided for certain repetitive code.

      Specified by:
      equals in class Query

    • 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
