the class JoinUtil method createJoinQuery.

/**
   * Method for query time joining for numeric fields. It supports multi- and single- values longs, ints, floats and longs.
   * All considerations from {@link JoinUtil#createJoinQuery(String, boolean, String, Query, IndexSearcher, ScoreMode)} are applicable here too,
   * though memory consumption might be higher.
   * <p>
   *
   * @param fromField                 The from field to join from
   * @param multipleValuesPerDocument Whether the from field has multiple terms per document
   *                                  when true fromField might be {@link DocValuesType#SORTED_NUMERIC},
   *                                  otherwise fromField should be {@link DocValuesType#NUMERIC}
   * @param toField                   The to field to join to, should be {@link IntPoint}, {@link LongPoint}, {@link FloatPoint}
   *                                  or {@link DoublePoint}.
   * @param numericType               either {@link java.lang.Integer}, {@link java.lang.Long}, {@link java.lang.Float}
   *                                  or {@link java.lang.Double} it should correspond to toField types
   * @param fromQuery                 The query to match documents on the from side
   * @param fromSearcher              The searcher that executed the specified fromQuery
   * @param scoreMode                 Instructs how scores from the fromQuery are mapped to the returned query
   * @return a {@link Query} instance that can be used to join documents based on the
   *         terms in the from and to field
   * @throws IOException If I/O related errors occur
