Class MultiLongValues

  • public abstract class MultiLongValues
    extends Object
    Per-segment, per-document long values, which can be calculated at search-time. Documents may produce multiple values. See also LongValues for a single-valued version.

    Currently meant only for use within the faceting module. Could be further generalized and made available for more use-cases outside faceting if there is a desire to do so.

    WARNING: This API is experimental and might change in incompatible ways in the next release.
