{"t1":{"dynamic_templates":[{"no_analyze_strings":{"mapping":{"index":"not_analyzed","type":"string"},"match_mapping_type":"string","match":"*"}}],"properties":{"date_opt_time":{"format":"dateOptionalTime","type":"date"},"basic_date":{"index":"not_analyzed","type":"string"}}}}

^^^ Date optional time format was correctly parsed as a date, and basic_date_time format was not, so because no_analyze_strings is defined it's not analyzed. That's correct.

But in our app we use basic_date_time format so we defined it as default format:

curl -XPUT http://localhost:9200/i/t2/_mapping -d '
{ "t2" :  {
          "date_formats" : [ "basic_date_time" ],
          "dynamic_templates" : [
            {
              "no_analyze_strings" : {
                "match_mapping_type" : "string",
                "match" : "*",
                "mapping" : {
                  "type" : "string",
                  "index" : "not_analyzed"
                }
              }
            }]
        }}'

curl -XPUT http://localhost:9200/i/t2/1 -d '
{ "basic_date" : "20120209T180027.513+0100", "date_opt_time" : "2012-02-09T18:00:27.513+0100"} '

curl -XGET http://localhost:9200/i/t2/_mapping
{"t2":{"dynamic_templates":[{"no_analyze_strings":{"mapping":{"index":"not_analyzed","type":"string"},"match_mapping_type":"string","match":"*"}}],"properties":{"date_opt_time":{"index":"not_analyzed","type":"string"},"basic_date":{"index":"not_analyzed","type":"string"}},"dynamic_date_formats":["basic_date_time"]}}

^^^ And here is the problem. "date_opt_time" was not recognized as a date which is correct, but why "basic_date" wasn't?
