Can someone explain the difference between _source field present vs not
present in an index?
I tried one example but couldn't figure out what difference does it make to
have or not have _source field -
_SOURCE FIELD ADDED IN MAPPING:
drwxrwxr-x 2 local local 4096 Sep 16 17:00 logs
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$ curl -XDELETE
localhost:9200/test
{"ok":true,"acknowledged":true}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
curl -XPOST localhost:9200/test -d '{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"type1" : {
"_source" : { "enabled" : true },
"properties" : {
"field1" : { "type" : "string", "index" : "not_analyzed" }
}
}
}
}'
{"ok":true,"acknowledged":true}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
SEARCHING SHOWS _SOURCE FIELD IS THERE -
/elasticsearch-0.90.3$ curl -XGET localhost:9200/test/test/_search?q=key:"2"
{"took":9,"timed_out":false,"_shards":{"total":1,"successful":1,"failed":0},"hits":{"total":1,"max_score":0.19178301,"hits":[{"_index":"test","_type":"test","_id":"2","_score":0.19178301,
"_source" :
{"key":"value
2"}}]}}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
MAKING _SOURCE FIELD FALSE NOW -
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$ curl -XDELETE
localhost:9200/test
{"ok":true,"acknowledged":true}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
curl -XPOST localhost:9200/test -d '{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"type1" : {
"_source" : { "enabled" : false },
"properties" : {
"field1" : { "type" : "string", "index" : "not_analyzed" }
}
}
}
}'
{"ok":true,"acknowledged":true}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$ curl -XPUT
localhost:9200/test/test/2 -d '{"key":"value 2"}'
{"ok":true,"_index":"test","_type":"test","_id":"2","_version":1}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
SEARCHING AGAIN - STILL _SOURCE FIELD IS THERE
local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$ curl -XGET
localhost:9200/test/test/_search?q=key:"2"
{"took":2,"timed_out":false,"_shards":{"total":1,"successful":1,"failed":0},"hits":{"total":1,"max_score":0.19178301,"hits":[{"_index":"test","_type":"test","_id":"2","_score":0.19178301,
"_source" : {"key":"value
2"}}]}}local@pldsvv-07:/var/elasticsearch/elasticsearch-0.90.3$
Not sure what i achieved by adding or making it false. If someone can
explain it would be great.
Thanks
