[[search-uri-request]]
== URI Search
A search request can be executed purely using a URI by providing request
parameters. Not all search options are exposed when executing a search
using this mode, but it can be handy for quick "curl tests". Here is an
example:
[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/twitter/tweet/_search?q=user:kimchy'
--------------------------------------------------
And here is a sample response:
[source,js]
--------------------------------------------------
{
"_shards":{
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits":{
"total" : 1,
"hits" : [
{
"_index" : "twitter",
"_type" : "tweet",
"_id" : "1",
"_source" : {
"user" : "kimchy",
"postDate" : "2009-11-15T14:12:12",
"message" : "trying out Elasticsearch"
}
}
]
}
}
--------------------------------------------------
[float]
=== Parameters
The parameters allowed in the URI are:
[cols="<,<",options="header",]
|=======================================================================
|Name |Description
|`q` |The query string (maps to the `query_string` query, see
<<query-dsl-query-string-query,_Query String
Query_>> for more details).
|`df` |The default field to use when no field prefix is defined within the
query.
|`analyzer` |The analyzer name to be used when analyzing the query string.
|`default_operator` |The default operator to be used, can be `AND` or
`OR`. Defaults to `OR`.
|`explain` |For each hit, contain an explanation of how scoring of the
hits was computed.
|`_source`| added[1.0.0.Beta1]Set to `false` to disable retrieval of the `_source` field. You can also retrieve
part of the document by using `_source_include` & `_source_exclude` (see the <<search-request-source-filtering, request body>>
documentation for more details)
|`fields` |The selective stored fields of the document to return for each hit,
comma delimited. Not specifying any value will cause no fields to return.
|`sort` |Sorting to perform. Can either be in the form of `fieldName`, or
`fieldName:asc`/`fieldName:desc`. The fieldName can either be an actual
field within the document, or the special `_score` name to indicate
sorting based on scores. There can be several `sort` parameters (order
is important).
|`track_scores` |When sorting, set to `true` in order to still track
scores and return them as part of each hit.
|`timeout` |A search timeout, bounding the search request to be executed
within the specified time value and bail with the hits accumulated up to
that point when expired. Defaults to no timeout.
|coming[1.4.0] `terminate_after` |The maximum number of documents to collect for
each shard, upon reaching which the query execution will terminate early.
If set, the response will have a boolean field `terminated_early` to
indicate whether the query execution has actually terminated_early.
Defaults to no terminate_after.
|`from` |The starting from index of the hits to return. Defaults to `0`.
|`size` |The number of hits to return. Defaults to `10`.
|`search_type` |The type of the search operation to perform. Can be
`dfs_query_then_fetch`, `dfs_query_and_fetch`, `query_then_fetch`,
`query_and_fetch`, `count`, `scan`. Defaults to `query_then_fetch`. See
<<search-request-search-type,_Search Type_>> for
more details on the different types of search that can be performed.
|`lowercase_expanded_terms` |Should terms be automatically lowercased or
not. Defaults to `true`.
|`analyze_wildcard` |Should wildcard and prefix queries be analyzed or
not. Defaults to `false`.
