Indices Queryedit

Deprecated in 5.0.0.

Search on the _index field instead

The indices query is useful in cases where a search is executed across multiple indices. It allows to specify a list of index names and an inner query that is only executed for indices matching names on that list. For other indices that are searched, but that don’t match entries on the list, the alternative no_match_query is executed.

GET /_search
    "query": {
        "indices" : {
            "indices" : ["index1", "index2"],
            "query" : { "term" : { "tag" : "wow" } },
            "no_match_query" : { "term" : { "tag" : "kow" } }

You can use the index field to provide a single index.

no_match_query can also have "string" value of none (to match no documents), and all (to match all). Defaults to all.

query is mandatory, as well as indices (or index).
