Hi,  
I want for a test indexing data with 2 fields and after that, i want  
add fields with "update".

I've try :

for($i=1; $i \< 4; $i++){  
if($i == 1){  
$result = $es-\>index(  
index =\> "toto",  
type =\> "tata",  
id =\> 1,  
data =\> {  
name =\> "big",  
surname =\> "muzzy"  
},  
);  
}  
else{  
print "tag : "; #name of the new tag  
chomp($tag = );

```
						$result = $es->update(
							index => "toto",
							type => "tata",
							id => 1,

							script => "_fields[$tag].value+=[tag]", #Doesn't work, don't

```

know how it's works  
params =\> {$tag =\> 'ok'}  
);  
}  
}

My main problem comes from the script, if you see other errors you can  
tell me too.  
So :

I'll send an SOS to the world  
I hope that someone gets my  
Message in a forum

Thanks !

I think in the update operation you should use ctx.\_source instead of  
\_fields.

ctx is just a map that currently contain one value "\_source", which is  
another map containing all fileds in your document parsed into a map. So,

"script" : "ctx.\_source["tag"] = ["foo"]"

will create a new field called tag with value "foo" and

"script" : "ctx.\_source["tag"] += ["bar"]"

will create add another value "bar" to the filed.

You can combine these two operations together by checking if field already  
exists first:

"script" : "if(ctx.\_source["tag"]==null) { ctx.\_source["tag"] =  
["foo"]} else {ctx.\_source["tag"] += ["foo"]}"

Hi !  
First, thanks for explain Igor.

I've try the ctx.\_source but doesn't works.

I show you the entire script (little script just to test update  
function)

* * *

Script

* * *

#!/usr/bin/perl

use strict;  
use warnings;  
use ElasticSearch;

```
				my $es = ElasticSearch->new(
									        transport => 'http',

```

servers =\> 'localhost:9200',  
trace\_calls =\> 1,  
timeout =\> 30,  
max\_requests =\> 10\_000,

```
									        no_refresh => 0
										);

				my ($result, $tag);
				my $i;

				for($i=1; $i < 5; $i++){
					if($i == 1){
						$result = $es->index(
							index => "toto",
							type => "tata",
							id => 1,
							data => {
								name => "big",
								surname => "muzzy"
							},
						);
					}
					else{
						print "tag : ";
						chomp($tag = <STDIN>);

						$result = $es->update(
							index => "toto",
							type => "tata",
							id => 1,

							script => {"ctx._source[\"$tag\"].value=["foo"]"},
                                                            params

```

=\> {$tag =\> 'ok'}  
);  
}  
}

* * *

Error message

* * *

I think the problem is caused by { } around script text. It should be

script =\> "ctx.\_source["$tag"].value=["foo"]"
