Multisearch questions: facets and query string

Elastic Stack Elasticsearch
1

Hi,

I do a multisearch with:
{}
{"query" : { "term" : {"category" : "sport"} }, "facets" : {"text_t1" :
{"terms" : {"field" : "tags1", "size" : 20}}}}

{}
{"query" : { "term" : {"category" : "sport"} }, "facets" : {"text_t2" :
{"terms" : {"field" : "tags1", "size" : 20}}}}

(twice the exact same request).

And, I get:
$ curl -XGET 'localhost:9200/_msearch?search_type=count&pretty=1'
--data-binary @requests; echo
{
"responses" : [ {
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 6,
"max_score" : 0.0,
"hits" : [ ]
},
"facets" : {
"text_t1" : {
"_type" : "terms",
"missing" : 0,
"total" : 6,
"other" : 0,
"terms" : [ {
"term" : "extérieur",
"count" : 2
}, {
"term" : "autre",
"count" : 2
}, {
"term" : "nouveau",
"count" : 1
}, {
"term" : "intérieur",
"count" : 1
} ]
}
}
}, {
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 10,
"max_score" : 0.0,
"hits" : [ ]
}
} ]
}

Why do I get only text_t1 facet (and not text_t2)?
Why is the hits total different?

Last question: Is it possible to pass the queries as url parameter for a
multisearch (my client doesn't let me define bodies for GET requests)?

Thanks for your help.

Is there an empty line between both requests?
It should not.

If you can reproduce it, can you create a full curl recreation, gist it and open an issue?

Hi David,

As you pointed it, the problem was the empty line between the two requests.
For those who want to use the multi search API, note that the request file
must also end with an empty line.

Do you know if the multi search API can be used with query string as
parameter, as described
here Elasticsearch Platform — Find real-time answers at scale | Elastic ?
The documentation just says that not all search options are exposed,
without saying which are not exposed.

Thanks for your help.

As far as I can see, only search_type and ignore_indices parameters are supported in _msearch parameters.
So q=* does not work here.

So you should pass parameters using QueryDSL.

About documentation, I can read at the bottom of this page: Elasticsearch Platform — Find real-time answers at scale | Elastic the full list of supported parameters for _search end point.
