conn |
an Elasticsearch connection object, see |
index |
Only one index. Required |
id |
Document id, only one. Required |
type |
Only one document type, optional |
source2 |
(logical) Set to TRUE to retrieve the _source of the document
explained. You can also retrieve part of the document by using
source_include & source_exclude (see Get API for more details). This
matches the |
fields |
Allows to control which stored fields to return as part of the document explained. |
routing |
Controls the routing in the case the routing was used during indexing. |
parent |
Same effect as setting the routing parameter. |
preference |
Controls on which shard the explain is executed. |
source |
Allows the data of the request to be put in the query string of the url. |
q |
The query string (maps to the query_string query). |
df |
The default field to use when no field prefix is defined within the query. Defaults to _all field. |
analyzer |
The analyzer name to be used when analyzing the query string. Defaults to the analyzer of the _all field. |
analyze_wildcard |
(logical) Should wildcard and prefix queries be
analyzed or not. Default: |
lowercase_expanded_terms |
Should terms be automatically lowercased
or not. Default: |
lenient |
If set to true will cause format based failures (like
providing text to a numeric field) to be ignored. Default: |
default_operator |
The default operator to be used, can be AND or OR. Defaults to OR. |
source_exclude |
A vector of fields to exclude from the returned source2 field |
source_include |
A vector of fields to extract and return from the source2 field |
body |
The query definition using the Query DSL. This is passed in the body of the request. |
raw |
If |
... |
Curl args passed on to crul::HttpClient |
