Elastic search retrieving results with half the value - elasticsearch

Question

I am trying to check whether client_id is already exists in the index or not. but problem is ES still retrieving full ID, even though I am giving half of the id. here is the mapping.
'mappings': {
'properties': {
'client_id': {'index': 'true','type': 'keyword'},
'client_name': {'index': 'true', 'type': 'keyword'},
'data_index_server': {'type': 'ip'},
'data_file_node_path': {'index': 'true', 'type': 'keyword'},
}
If I have the record like this
{
"_index": "client_index",
"_type": "_doc",
"_id": "wYlkrYMB_q_jkYaCv6pU",
"_version": 1,
"_score": 1,
"_source": {
"doc": {
"client_id": "0935be6b-61fe-4ec4-80c8-5c5ee8384378",
"client_name": "citi",
"data_file_node_path": " ",
"data_index_server": " "
}
},
"fields": {
"doc.client_id": [
"0935be6b-61fe-4ec4-80c8-5c5ee8384378"
],
"doc.client_name": [
"sample_name"
],
"doc.data_index_server": [
" "
],
"doc.client_name.keyword": [
"citi"
],
"doc.data_file_node_path.keyword": [
" "
],
"doc.client_id.keyword": [
"0935be6b-61fe-4ec4-80c8-5c5ee8384378"
],
"doc.data_index_server.keyword": [
" "
],
"doc.data_file_node_path": [
" "
]
}
}
my request for search is this. and if I am taking some part of the ID and search against it. I am expecting to be hits will be zero
POST /client_index/_search
{
"query": {
"match": {
"doc.client_id":"0935be6b-61fe-4ec4-80c8" ,
}
}
}
I have follwed this url: How to make elastic search only match full field. change the fields type to keywords and also toggled index between true and false, but no result

Answer 1

I think you have mixed up few things, in the mapping you showed just four properties which are simple fields, while in the search response, it has additional fields under fields which are of type object.
You read it correct, keyword fields are not analyzed and on these fields you will get results only on full field value.
You should just try to define your client-id as a keyword field in new index with your sample field and search on that index to see it in action.
