# Search

}
}
}
```
{% include copy-curl.html %}

POST /<target-index>/_search
POST /_search
```
## URL Parameters

cancel_after_time_interval | Time | The time after which the search request will be canceled. Request-level parameter takes precedence over cancel_after_time_interval [cluster setting]({{site.url}}{{site.baseurl}}/api-reference/cluster-settings). Default is -1.
ccs_minimize_roundtrips | Boolean | Whether to minimize roundtrips between a node and remote clusters. Default is true.
default_operator | String | Indicates whether the default operator for a string query should be AND or OR. Default is OR.
df | String | The default field in case a field prefix is not provided in the query string.
docvalue_fields | String | The fields that OpenSearch should return using their docvalue forms.
expand_wildcards | String | Specifies the type of index that wildcard expressions can match. Supports comma-separated values. Valid values are all (match any index), open (match open, non-hidden indexes), closed (match closed, non-hidden indexes), hidden (match hidden indexes), and none (deny wildcard expressions). Default is open.
explain | Boolean | Whether to return details about how OpenSearch computed the document's score. Default is false.
from | Integer | The starting index to search from. Default is 0.
ignore_throttled | Boolean | Whether to ignore concrete, expanded, or indexes with aliases if indexes are frozen. Default is true.
ignore_unavailable | Boolean | Specifies whether to include missing or closed indexes in the response. Default is false.
lenient | Boolean | Specifies whether OpenSearch should accept requests if queries have format errors (for example, querying a text field for an integer). Default is false.
max_concurrent_shard_requests | Integer | How many concurrent shard requests this request should execute on each node. Default is 5.
pre_filter_shard_size | Integer | A prefilter size threshold that triggers a prefilter operation if the request exceeds the threshold. Default is 128 shards.
preference | String | Specifies the shards or nodes on which OpenSearch should perform the search. For valid values, see [The `preference` query parameter](#the-preference-query-parameter).
q | String | Lucene query strings query.
request_cache | Boolean | Specifies whether OpenSearch should use the request cache. Default is whether its enabled in the indexs settings.

routing | String | Value used to route the update by query operation to a specific shard.
scroll | Time | How long to keep the search context open.
search_type | String | Whether OpenSearch should use global term and document frequencies when calculating relevance scores. Valid choices are `query_then_fetch` and `dfs_query_then_fetch`. `query_then_fetch` scores documents using local term and document frequencies for the shard. Its usually faster but less accurate. `dfs_query_then_fetch` scores documents using global term and document frequencies across all shards. Its usually slower but more accurate. Default is `query_then_fetch`.
seq_no_primary_term | Boolean | Whether to return sequence number and primary term of the last operation of each document hit.
size | Integer | How many results to include in the response.
sort | List | A comma-separated list of &lt;field&gt; : &lt;direction&gt; pairs to sort by.

_source_includes | List | A comma-separated list of source fields to include in the response.
stats | String | Value to associate with the request for additional logging.
stored_fields | Boolean | Whether the get operation should retrieve fields stored in the index. Default is false.
suggest_field | String | Fields OpenSearch can use to look for similar terms.
suggest_mode | String | The mode to use when searching. Available options are `always` (use suggestions based on the provided terms), `popular` (use suggestions that have more occurrences), and `missing` (use suggestions for terms not in the index).
suggest_size | Integer | How many suggestions to return.
suggest_text | String | The source that suggestions should be based off of.
terminate_after | Integer | The maximum number of documents OpenSearch should process before terminating the request. Default is 0.
timeout | Time | How long the operation should wait for a response from active shards. Default is `1m`.
track_scores | Boolean | Whether to return document scores. Default is false.
track_total_hits | Boolean or Integer | Whether to return how many documents matched the query.
typed_keys | Boolean | Whether returned aggregations and suggested terms should include their types in the response. Default is true.
version | Boolean | Whether to include the document version as a match.
### The `preference` query parameter
The `preference` query parameter specifies the shards or nodes on which OpenSearch should perform the search. The following are valid values:
- `_primary`: Perform the search only on primary shards.
- `_replica`: Perform the search only on replica shards.
- `_primary_first`: Perform the search on primary shards but fail over to other available shards if primary shards are not available.
- `_replica_first`: Perform the search on replica shards but fail over to other available shards if replica shards are not available.
- `_local`: If possible, perform the search on the local node's shards.
- `_prefer_nodes:<node-id-1>,<node-id-2>`: If possible, perform the search on the specified nodes. Use a comma-separated list to specify multiple nodes.
- `_shards:<shard-id-1>,<shard-id-2>`: Perform the search only on the specified shards. Use a comma-separated list to specify multiple shards. When combined with other preferences, the `_shards` preference must be listed first. For example, `_shards:1,2|_replica`.
- `_only_nodes:<node-id-1>,<node-id-2>`: Perform the search only on the specified nodes. Use a comma-separated list to specify multiple nodes.
- `<string>`: Specifies a custom string to use for the search. The string cannot start with an underscore character (`_`). Searches with the same custom string are routed to the same shards.
