# Getting Documents¶

Like indexing documents, there are several ways to ‘get’ document(s) from the Elasticsearch server using elasticsearch-lua.

## Getting Single Document¶

To get a single document, provide index, type and id of the document.

local res, status = client:get{
index = "my_index",
type = "my_type",
id = "my_id"
}


## Getting Multiple Documents¶

Elasticsearch supports getting multiple documents using a single request. It is advised to use this method in case you want to retrieve multiple documents. You need to pass an array of Lua tables to the MGET API. Each table represents details about one document and consists of three fields _index, _type and _id.

local res, status = client:mget{
body = {
docs = {
-- First document
{
["_index"] = "my_index1",
["_type"] = "my_type1",
["_id"] = "my_id1"
},
-- Second document
{
["_index"] = "my_index2",
["_type"] = "my_type2",
["_id"] = "my_id2"
}
}
}
}


In case every document has the same index or type, they can be specified separately instead of passing them in every document table.

local res, status = client:mget{
index = "my_index",
type = "my_type",
body = {
docs = {
-- First document
{
["_id"] = "my_id1"
},
-- Second document
{
["_id"] = "my_id2"
}
}
}
}
