Elasticsearch: Template field in templates field name vagueness

[davebarda]

Description of the problem including expected versus actual behavior:
The short explaination:
The field template In templates is vague because it is pattern matching the indices which will be working on, I think that the name should be somthing like Index pattern or so.

The Long one:
First to mention, I have started to use elasticsearch today,
I have used a twitter template which I couldn't understand why is not working.
I have searched the template file maybe It contains the index name and thats the reason It didn't work , I have noticed that when I changed the index name to the template name everything was just fine so I understood that I need to write about Index templates and I have understood that there is an index pattern matching with the template name.

Do you have any recommendation?

[davebarda]

Well as I have wrote,
I think that index pattern should be suggestive,
It will make people are new to templates to check what is all about.

[jpountz]

OK, so something like:

PUT /_template/template_1
{
  "index_pattern": "te*",
  "settings": {
    "number_of_shards": 1
  }
}

rather than

PUT /_template/template_1
{
  "template": "te*",
  "settings": {
    "number_of_shards": 1
  }
}

I agree - I've never liked that template parameter.

Depending on which gets in first, also see https://github.com/elastic/elasticsearch/pull/17300
