This is business log stat app in development.  
I used version of elasticsearch is 0.90.1

$curl -XGET '[http://192.168.11.107:9200/](http://192.168.11.107:9200/)'

There is some example data,I use ISO dateformat:

And I meet problem when I use "Web front-end over elasticsearch data" list  
in Elasticsearch client page. I encounter exception on time field.

Hi Lei Xiao Bao

I am new to Elasticsearch (less than 1 month) but already have seen it  
being quite picky about some things (maybe it lacks some extra code in the  
parsing stages)...  
For example, I got a problem yesterday using an index name with CamelCase.

Maybe Elasticsearch does not like your date format, with that big "T" in  
between...  
"time":"2013-06-15T00:00:00"

The system error that you show, in my humble opinion, prints in a different  
format :  
[2013-06-15 17:42:41,781][DEBUG][action.search.type] [Ape]  
[syslog][1],

Just my 5 cents.

Yes... It looks that way. You are right it.  
Even so... In the same documentation page that you mentioned I found  
this... (see pasted text below).

Look at the example, he includes a specific string to format the date.  
Maybe doing that may help.

(I really do not know, as I said, I am new to Elasticsearch, but... Your  
problem is interesting so I am just trying to help).

date

The date type is a special type which maps to JSON string type. It follows  
a specific format that can be explicitly set. All dates are UTC.  
Internally, a date maps to a number type long, with the added parsing stage  
from string to long and from long to string. An example mapping:

{  
"tweet" : {  
"properties" : {  
"postDate" : {  
"type" : "date",  
"format" : "YYYY-MM-dd"  
}  
}  
}  
}

The date type will also accept a long number representing UTC milliseconds  
since the epoch, regardless of the format it can handle.

As I tried ,a bad date format data insert will throw a FormatException  
cause data reject by server.

In my test i inserted 100,000 rows successful .

Maybe I can test a fewer data first.

Well, after some more tests. I think I found where the problem is.

I write it down for anyone reference:

current now ,The problem happens when u changed field type. es can not  
changed field type at runtime. If u found some field type error at test  
time.u must -XDELTE all and -XPUT \_mapping and -XPUT data again.

Then that cast exception happens. after query data 2nd time. I thinik ES  
cached filed type and not flush cache when mapping changed.

Restart ES may solve this problem.
