How to perform indices query in ElasticSearch?

Question

What URL do you use to perform an indices query?

I see the following here, but what is the URL to do it too? http://www.elasticsearch.org/guide/reference/query-dsl/indices-query.html

The only way I know how to query in elastic search is with the URI:

http://localhost:9200/myindex

The issue I am having is I have multiple indexes with different documents myindex1 myindex2 myindex3

and I want to be able to just perform any query on myindex1 and myindex2 (or just myindex2 and myindex3)

Is this possible? Also can you combine index query with QueryDSL like match_all query or Terms Query:

http://www.elasticsearch.org/guide/reference/query-dsl/terms-query.html

Please show an example of a sample URL, and what goes in the body of the request if possible so I can get an idea.

Answer 1

You could try:

 curl http://localhost:9200/myindex1,myindex2/_search?q=*

Or

 curl -XPOST http://localhost:9200/myindex1,myindex2/_search -d '{
    // your query here
 }'

Is it what you are looking for?

Answer 2

If you are using sense plugin you can write like this

 POST myindex1/_search
{
"query": {"match_all": {}}
 }

Answer 3

You could do this a couple of different ways.

1) With an indices query on myindex1 and myindex2 with a terms query on the title field.

curl -XPOST http://localhost:9200/_search -d '{
  "query": {
    "indices": {
      "indices": [
        "myindex1",
        "myindex2"
      ],
      "query": {
        "terms": {
          "title": [
            "foo",
            "bar"
          ]
        }
      }
    }
  }
}'

2) By specifying the indices you want to search in the URI (with the same exact terms query).

curl -XPOST http://localhost:9200/myindex1,myindex2/_search -d '{
  "query": {
    "terms": {
      "title": [
        "cookies",
        "cake"
      ]
    }
  }
}'

And yes, you can swap out the terms query for a match_all query (or any other query here, really) in either of the two examples. Here's how you would do a match_all query in the second example:

curl -XPOST http://localhost:9200/myindex1,myindex2/_search -d '{
  "query": {
    "match_all": {}
  }
}'
