Constructor Details

ScriptSortBuilder

public ScriptSortBuilder(Script script,
 ScriptSortBuilder.ScriptSortType type)

Constructs a script sort builder with the given script.

Parameters:

script - The script to use.

type - The type of the script, can be either ScriptSortBuilder.ScriptSortType.STRING or ScriptSortBuilder.ScriptSortType.NUMBER

ScriptSortBuilder

public ScriptSortBuilder(StreamInput in)
                  throws IOException

Read from a stream.

Throws:

IOException

Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Throws:

IOException

script

public Script script()

Get the script used in this sort.

type

public ScriptSortBuilder.ScriptSortType type()

Get the type used in this sort.

sortMode

public ScriptSortBuilder sortMode(SortMode sortMode)

Defines which distance to use for sorting in the case a document contains multiple values.
For ScriptSortBuilder.ScriptSortType.STRING, the set of possible values is restricted to SortMode.MIN and SortMode.MAX

sortMode

public SortMode sortMode()

Get the sort mode.

setNestedFilter

@Deprecated
public ScriptSortBuilder setNestedFilter(QueryBuilder nestedFilter)

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Sets the nested filter that the nested objects should match with in order to be taken into account for sorting.

getNestedFilter

@Deprecated
public QueryBuilder getNestedFilter()

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Gets the nested filter.

setNestedPath

@Deprecated
public ScriptSortBuilder setNestedPath(String nestedPath)

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Sets the nested path if sorting occurs on a field that is inside a nested object. For sorting by script this needs to be specified.

getNestedPath

@Deprecated
public String getNestedPath()

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Gets the nested path.

getNestedSort

public NestedSortBuilder getNestedSort()

Returns the NestedSortBuilder

setNestedSort

public ScriptSortBuilder setNestedSort(NestedSortBuilder nestedSort)

Sets the NestedSortBuilder to be used for fields that are inside a nested object. The NestedSortBuilder takes a `path` argument and an optional nested filter that the nested objects should match with in order to be taken into account for sorting.

toXContent

public org.elasticsearch.common.xcontent.XContentBuilder toXContent(org.elasticsearch.common.xcontent.XContentBuilder builder,
 org.elasticsearch.common.xcontent.ToXContent.Params builderParams)
                                                             throws IOException

Throws:

IOException

fromXContent

public static ScriptSortBuilder fromXContent(org.elasticsearch.common.xcontent.XContentParser parser,
 String elementName)

Creates a new ScriptSortBuilder from the query held by the XContentParser in XContent format.

Parameters:

parser - the input parser. The state on the parser contained in this context will be changed as a side effect of this method call

elementName - in some sort syntax variations the field name precedes the xContent object that specifies further parameters, e.g. in '{ "foo": { "order" : "asc"} }'. When parsing the inner object, the field name can be passed in via this argument

Description copied from interface: Rewriteable

Rewrites this instance based on the provided context. The returned objects will be the same instance as this if no changes during the rewrite were applied.

Throws:

IOException
