Lots of people read these forums, and many of them will simply skip over a post that is difficult to read, because it's just too large an investment of their time to try and follow a wall of badly formatted text.
If your goal is to get an answer to your questions, it's in your interest to make it as easy to read and understand as possible.
Please update your post.

Now I want to perform _analyze in _doc/1

You can't really. But why do you want to do this?
You can analyze the text that you sent within this document though to understand what happened behind the scene with:

GET my_index/_analyze
{
  "field" : "container.para",
  "text" : [ 
     "Issuer not, and will not permit any of its Restricted Subsidiaries to, the Consolidated Fixed Charge Coverage Ratio for the most recently end Indebtedness is Incurred is at least 2.0 to 1.0", 
     "If the debt covenant is redeeming or purchasing less than all of the Secured Notes issued under the Secured Indenture at any time." 
  ]
