java.lang.Enum<SearchType>

org.elasticsearch.action.search.SearchType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<SearchType>

public enum SearchType
extends java.lang.Enum<SearchType>

Search type represent the manner at which the search operation is executed.

Enum Constant Summary

Enum Constants

Enum Constant	Description
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.
QUERY_AND_FETCH	Deprecated.
QUERY_THEN_FETCH	The query is executed against all shards, but only enough information is returned (not the document content).

Field Summary

Fields

Modifier and Type	Field	Description
static SearchType	DEFAULT	The default search type (QUERY_THEN_FETCH.

Method Summary

Modifier and Type	Method	Description
static SearchType	fromId(byte id)	Constructs search type based on the internal id.
static SearchType	fromString(java.lang.String searchType)	The a string representation search type to execute, defaults to DEFAULT.
byte	id()	The internal id of the type.
static SearchType	valueOf(java.lang.String name)	Returns the enum constant of this type with the specified name.
static SearchType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

DFS_QUERY_THEN_FETCH

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.

QUERY_THEN_FETCH

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).

QUERY_AND_FETCH

@Deprecated
public static final SearchType QUERY_AND_FETCH

Deprecated.

Only used for pre 5.3 request where this type is still needed

Field Detail

DEFAULT

public static final SearchType DEFAULT

The default search type (QUERY_THEN_FETCH.

Method Detail

values

public static SearchType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SearchType c : SearchType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SearchType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.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(java.lang.String searchType)

The a string representation search type to execute, defaults to DEFAULT. Can be one of "dfs_query_then_fetch"/"dfsQueryThenFetch", "dfs_query_and_fetch"/"dfsQueryAndFetch", "query_then_fetch"/"queryThenFetch" and "query_and_fetch"/"queryAndFetch".
