Postings Highlighter

If index_options is set to offsets in the mapping.
The postings highlighter:
        1. Faster.
        2. Less Disk Space.
        3. Breaks the text into sentences and highlights them.
        4. Treats the document as the whole corpus, and scores individual sentences.

Here is an example of setting the content field to allow for highlighting using the postings highlighter on it:
