Is there any way to pass search query in POST parameter rather than body?

Elastic Stack Elasticsearch
1

Hello,

For complete functionality, UI framework I use needs query be passed in
POST parameters rather than body. Is there any way I can pass complete
query I would normally pass in the body in POST parameter.

Using GET and URI is not an option - I need full query DSL

Thank you,
Alex

I found a partial answer. one can pass complete query in GET source
parameter. But the query I generate (with facet, facet filters + filtered
(based on selected facet values) query can rather long. I would be more
comfortable passing it as post parameter. I tried post with source
parameter but unfortunately it does not work:

{"error":"SearchPhaseExecutionException[Failed to execute phase
[query_fetch], total failure; shardFailures{[pguRRu2dTzKk_AMMcUO32w][award][0]: SearchParseException[[award][0]:
from[-1],size[-1]: Parse Failure [Failed to parse source [na]]]; nested:
ElasticSearchParseException[Failed to derive xcontent fromorg.elasticsearch.common.bytes.ChannelBufferBytesReference@61f0ab21];
}]","status":500}

Sorry. I don't understand. What do you mean by POST?
This?

curl -XPOST 'http://localhost:9200/twitter/tweet/_search' -d '{
"query": {
"filtered" : {
"query" : {
"query_string" : {
"query" : "some query string here"
}
},
"filter" : {
"term" : { "user" : "kimchy" }
}
}
}
}
'

I mean passing query in form-encoded parameters via POST as supposed to
passing it in request body in raw
just like with get you can pass parameters via query string, with post you
can pass then form-encoded. web server (say servlet API) then would extract
them and present it to you as parameters

I don't think you can. See Jörg answer: https://groups.google.com/d/msg/elasticsearch/SzF0LhiVvqk/htn52x3xgmoJ

That said, you can do something like:

curl -XGET http://localhost:9200/_search?source=YOUR_JSON_HERE

curl 'localhost:9200/_search?source={"query":{"term":{"user":"kimchy"}}}'

Does it help?

I am already doing it with GET and source parameter and it works well. One
huge benefit is that size and start (and hopefully sort but have not tested
it yet) url parameters override whatever is in source={...} - big help
integrating with UI components that manage paging and generate these http
parameters

Now the problem is that for all practical purposes uri length is limited to
2000 characters so GET may very well fail with bigger queries (as I said
query with facet based "filtered", facets themselves, filters.... can get
pretty long plus of course url-encoding of all spaces and {} )

I wish the same functionality were available via POST. Couldn't ES check
encoding in POST header and if it is *application/x-www-form-urlencoded *just
extract encoded parameters and use source parameter just like it does with
GET?

Do you think I should put an enhancement request into Git?

I had a similar issue.
I manged to get the parameters from the post by doing:

@Override

public void handleRequest(final RestRequest request, final RestChannel
channel) {

Map<String,String> params = new HashMap<String, String>();
RestUtils.decodeQueryString(request.content().toUtf8(), 0, params);
String paramValue = params.get("parameter");

//DO SOMETHING

}

Notice that the json query you want to pass in doesn't need to be encoded
on the client side (with an Http.GET it needs to be)

Hope that helps

Thanks Kelsey that could be useful. I managed to get my UI framework
(ExtJS) to play better with POST so I am not dependent on having to use GET
any more
