Property Value

Type	Description
string

DocValueFields

Comma-separated list of fields to return as the docvalue representation of a field for each hit.

Declaration

public string[] DocValueFields { get; set; }

IgnoreThrottled

Whether specified concrete, expanded or aliased indexes should be ignored when throttled.

Declaration

public bool? IgnoreThrottled { get; set; }

Property Value

Type	Description
bool?

IgnoreUnavailable

Whether specified concrete indexes should be ignored when unavailable (missing or closed).

Declaration

public bool? IgnoreUnavailable { get; set; }

Property Value

Type	Description
bool?

Lenient

Specify whether format-based query failures (such as providing text to a numeric field) should be ignored.

Declaration

public bool? Lenient { get; set; }

Property Value

Type	Description
bool?

MaxConcurrentShardRequests

The number of concurrent shard requests per node this search executes concurrently. This value should be used to limit the impact of the search on the cluster in order to limit the number of concurrent shard requests.

Declaration

public long? MaxConcurrentShardRequests { get; set; }

Property Value

Type	Description
long?

PreFilterShardSize

Threshold that enforces a pre-filter round-trip to prefilter search shards based on query rewriting if the number of shards the search request expands to exceeds the threshold. This filter round-trip can limit the number of shards significantly if for instance a shard can not match any documents based on its rewrite method, that is if date filters are mandatory to match but the shard bounds and the query are disjoint.

Declaration

public long? PreFilterShardSize { get; set; }

Property Value

Type	Description
long?

Preference

Specify the node or shard the operation should be performed on.

Declaration

public string Preference { get; set; }

Property Value

Type	Description
string

QueryOnQueryString

Query in the Lucene query string syntax.

Declaration

public string QueryOnQueryString { get; set; }

Property Value

Type	Description
string

RequestCache

Specify if request cache should be used for this request or not, defaults to index level setting.

Declaration

Property Value

Type	Description
string[]

Scroll

Specify how long a consistent view of the index should be maintained for scrolled search.

Declaration
