  • Enum Constant Details


      public static final SearchType DFS_QUERY_THEN_FETCH
      Same as QUERY_THEN_FETCH, except for an initial scatter phase which goes and computes the distributed term frequencies for more accurate scoring.

      public static final SearchType QUERY_THEN_FETCH
      The query is executed against all shards, but only enough information is returned (not the document content). The results are then sorted and ranked, and based on it, only the relevant shards are asked for the actual document content. The return number of hits is exactly as specified in size, since they are the only ones that are fetched. This is very handy when the index has a lot of shards (not replicas, shard id groups).
  • Field Details


      public static final SearchType DEFAULT
      The default search type (QUERY_THEN_FETCH.

      public static final SearchType[] CURRENTLY_SUPPORTED
      Non-deprecated types
  • Method Details

    • values

      public static SearchType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static SearchType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
    • id

      public byte id()
      The internal id of the type.
    • fromId

      public static SearchType fromId(byte id)
      Constructs search type based on the internal id.
    • fromString

      public static SearchType fromString(String searchType)
      The a string representation search type to execute, defaults to DEFAULT. Can be one of "dfs_query_then_fetch" or "query_then_fetch".
