  [NOTE]
  ==================================
  As written above, this template is not valid JSON because it includes the
  _section_ markers like `{{#line_no}}`.  For this reason, the template should
  either be stored in a file (see <<pre-registered-templates>>) or, when used 
  via the REST API, should be written as a string:
  
  [source,json]
  --------------------
  "template": "{\"query\":{\"filtered\":{\"query\":{\"match\":{\"line\":\"{{text}}\"}},\"filter\":{{{#line_no}}\"range\":{\"line_no\":{{{#start}}\"gte\":\"{{start}}\"{{#end}},{{/end}}{{/start}}{{#end}}\"lte\":\"{{end}}\"{{/end}}}}{{/line_no}}}}}}"
