Hello All,

I am trying to index a document with escaped JSON string as a field. This  
field is a JSON representation of a legal document.

I want to extract the document text for analysis (the string also includes  
formatting data e.g. style info, paragraph info, line breaks etc ).  
So far I have tried to use a transform script to do this, my approach has  
been to write a script that

1. Converts the string to JSON object
2. Load a mustache template
3. Use mustache template to extract text for analysis

This has not worked so the question is

Is this possible?  
If not, is there another approach I can use?

I would prefer to use the transform approach as the content does not change  
and this step is only required for analysis.

Many thanks

OJS
