I have a query regarding the "transform" element in ES template mapping. I have been trying to figure out ways to add pathlevel to tokens generated by path\_hierarchy tokenizer.

Say I have a value like -

/a/b/c

path hierarchy gives me

/a  
/a/b  
/a/b/c

But I want to add pathlevel to it. I came across this piece while googling -

"transform": {  
"lang": "groovy",  
"script": "def splitPath = [];splitPath = ctx.\_source['request'].split('/'); ctx.\_source['pathDepth'] =splitPath.length; for (i = 1; splitPath.length \> i; i++) { ctx.\_source['pathLevel' + i] =splitPath[i] }"  
},

I thought I could use it for my case. But it errors out with -  
"error"=\>{"type"=\>"mapper\_parsing\_exception", "reason"=\>"Failed to parse mapping [dummy\_temp]: No type specified for field [transform]"  
This is the mapping I have

"request": {  
"type": "string",  
"index": "not\_analayzed",  
"fields": {  
"tree": {  
"type": "string",  
"analyzer": "analyzer\_path\_tokens",

"analyzer": "analyzer\_path\_tokens"  
},

This is the analyzer definition

"analyzer": {  
"analyzer\_path\_tokens": {  
"type": "custom",  
"tokenizer": "path\_hierarchy"  
}  
}

Please advise.
