the high order template can not overwrite the lower order template

[nshfany]

hello!
Elasticsearch version : elasticsearch 6.8.15

Steps to reproduce:

1. defined two template
   PUT _template/test_1 { "order":1, "index_patterns" : [ "test_*" ], "mappings":{ "_doc":{ "properties":{ "name":{ "ignore_above" : 10922, "type" : "keyword" } } } } }
PUT _template/test { "order":0, "index_patterns" : [ "test*" ], "mappings":{ "_doc":{ "properties":{ "name":{ "ignore_above" : 10922, "type" : "keyword", "index":false } } } } }
2. write two index test and test_1
PUT test/_doc/1 { "name":"Tom" }
PUT test_1/_doc/1 { "name":"Tom" }
3. get the two index test and test_1
GET test/_mapping
GET test_1/_mapping
4. the mapping of index test_1 is match the template test

the elasticsearch server has not any the error message!

@nshfany legacy index templates (the ones used here) are merged, which is why test_1 matches both templates. This is one of the downsides of legacy templates and has been addressed by composable index templates (#53101) released in 7.9+

Since this behavior is not a bug, I'm going to close this issue.

Oh~ thanks! This is a fantastic idea! The problem has been solved satisfactorily by the function of V2 template
