Empty Search
editEmpty Search
editLet’s start with the simplest form of the search
API, the empty search,
which returns all documents in all indices:
Just as with a query-string search, you can search on one, many, or _all
indices, and one, many, or all types:
GET /index_2014*/type1,type2/_search {}
And you can use the from
and size
parameters for pagination:
GET /_search { "from": 30, "size": 10 }
We present aggregations in depth in Aggregations, but for now, we’re going to focus just on the query.
Instead of the cryptic query-string approach, a request body search allows us to write queries by using the query domain-specific language, or query DSL.
