Incorrect prefix query results

Elastic Stack Elasticsearch
1

prefix query is not returning the correct results..
in ISO Country data.. my query was

{"query":{"bool":{"must":[{"prefix":{"country.name":"in"}}],"must_not":[],"should":[]}},"from":0,"size":50,"sort":[],"facets":{}}
and the returned result is:
{ took: 3 timed_out: false _shards: { total: 5 successful: 5 failed: 0 }
hits: { total: 3 max_score: 1 hits: [ { _index: restdb _type: country _id:
sX3-aNGBQaOjo-L7zNj7qQ _score: 1_source: { id: 519fcbce820ea8950373612b code
: ID name: INDONESIA } }{ _index: restdb _type: country _id:
YMXpIxaPRzmkMZqaKQ36pw _score: 1_source: { id: 519fcbce820ea895037360e4 code
: IO name: BRITISH INDIAN OCEAN TERRITORY }}{ _index: restdb _type:
country _id: Ok9MHCr4RLqjH6oFLX92EA _score: 1_source: { id:
519fcbce820ea8950373612a code: IN name: INDIA }}
] } }

As, you can see, red coloured data, is not matching prefix query..
Am i correct i need to do something else.., if not please help me to find
out correct way to do so, else, give me go ahead, to post this as bug.

Because your field is analyzed and broken into token.
So, country.name is indexed as: british,indian,ocean,territory

indian match the PrefixQuery in.

If you set this field to not_analyzed then, you will have to search for IN (uppercase).
