Logstash query template

Change from original question

{
  "query": {
    "bool": {
      "must": {
        "query_string": {
          "query": "id=%{id}"
        }
      },
      "filter": {
        "range" : {
            "timestamp" : {
              "gt" : "now-1h",
              "lt" : "now"
            }
        }
      }
    }
  }
}

I paste this into a template.json file and changed my elasticsearch to

elasticsearch {
                hosts => [ "localhost:9200" ]
                index => "${input}"
                query_template => "template.json"
}

And this results in an error. reason=>"Something is wrong with your configuration."
Not sure how to work around this? I looked at samples on elastic.co and looks as simple as this. I tried copying the whole path, but did not solve the problem.

Why not just use a date range filter in your query? I believe reasonably recent versions of ES are quite efficient in skipping indexes that obviously don't contain any documents in range (i.e. using logstash-* isn't significantly slower)

Wasn't sure if applying a date range would have applied to looking for the correct index. Am I suppose to write it within parameters filter of elasticsearch? I came up with a solution by parsing the timestamp and aggregate it to my index query name instead of using a 2-days date range. Not sure about the solution tho, do you have any opinion/suggestion?

You don't need to figure out which indexes to query. Just use a wildcard.

What do you mean by "parameters filter"?

If I wanted to apply a date range in the query, how would I use it within elasticsearch plug in? This ElasticSearch Parameters Plugin

Say give or take you have 90 indexes, would wildcard vs specific index contribute to speed? I thought it would since took's average value is less than that of a wildcard search

That's the elasticsearch output plugin, but you seem to be asking about the elasticsearch input or filter plugin.

Then I'm surprised. I was under the impression that the different would be far less noticeable.

I am trying to test the wildcard with date range, to see if it'll make any difference

GET logstash-*/_search
{
  "query": {
    "bool": {
      "must": {
        "query_string": {
          "query": "id=%{id}"
        }
      },
      "filter": {
        "range" : {
            "timestamp" : {
              "gt" : "now-1h",
              "lt" : "now"
            }
        }
      }
    }
  }
}

I paste this into a template.json and changed my elasticsearch to

elasticsearch {
                hosts => [ "localhost:9200" ]
                index => "${input}"
                query_template => "template.json"
}

And this results in an error. reason=>"Something is wrong with your configuration." Not sure how to work around this?

Nevermind. Found the error.

Unknown setting 'query_template' for elasticsearch {:level=>:error}

Version error?

Yes, your elasticsearch filter plugin is most likely too old. Try upgrading it, or upgrade Logstash altogether.

Ahh... I cant really just upgrade logstash/elasticsearch... do you have any alternative suggestions? Can I somehow squeeze all of the template into query in elasticsearch filter plugin?

Can I somehow squeeze all of the template into query in elasticsearch filter plugin?

Sure, just stuff it into a single string like in the examples in the documentation. It won't look nice but it'll work.

Thanks for the response Magnus. I have tried following this documentation Elasticsearch filter plugin and squeeze all of the query on one line, but I am obtaining a fetched an invalid config file error

Possibly due to quotes within query => " "bool" : ... "?

I tried doing something like query => " 'bool': ..." and now the resulting error message is
"reason":"Failed to parse query
"reason":{"type":"query_shard_exception","reason":"Failed to parse query
"reason":"Encountered \" <RANGE_GOOP>

My problem is very similar to the issue v0it has

Nvm. Solved my own question. Had to use lucene format.

query => '"id":%{id} AND @timestamp:[now-5h/d TO now/d]'
