Hi Team,  
Hope you are doing great..! I'm new to elasticsearch.  
I have an index with 100 document's. Now as per customer requirement i have created a new custom analyzer, now my question is i want that 100 documents analysed under my new analyzer.  
What is the procedure to get those 100 documents stored under my new custom analyzer.

Thanks in advance...
