  +The `fvh` highlighter uses the Lucene Fast Vector highlighter.
   This highlighter can be used on fields with `term_vector` set to
   `with_positions_offsets` in the mapping. The fast vector highlighter:
   
  -** Is faster especially for large fields (> `1MB`)
  -** Can be customized with  a <<boundary-scanners,`boundary_scanner`>>. 
  -** Requires setting `term_vector` to `with_positions_offsets` which

  +[[offsets-strategy]]
  +==== Offsets Strategy
   To create meaningful search snippets from the terms being queried,
   the highlighter needs to know the start and end character offsets of each word
   in the original text. These offsets can be obtained from:
  
positive.code: 
  pre_tags:: Use in conjunction with `post_tags` to define the HTML tags
  to use for the highlighted text. By default, highlighted text is wrapped
  in `<em>` and </em>` tags. Specify as an array of strings.
  
  post_tags:: Use in conjunction with `pre_tags` to define the HTML tags
  to use for the highlighted text. By default, highlighted text is wrapped
  
negative.code: fragmenter:: Specifies how text should be broken up in highlight
  snippets: `simple` or `span`. Only valid for the `plain` highlighter.
  Defaults to `span`.
  
  `simple`::: Breaks up text into same-sized fragments.
  `span`::: Breaks up text into same-sized fragments, but tried to avoid
  breaking up text between highlighted terms. This is helpful when you're
  querying for phrases. Default.
