Showing more of the highlighted context

Question

I am wondering how to make django-haystack highlight template tag show more of the text preceeding the highlight?

It currently shows "highlighted text some other text here" where it must show a bit more of the previous context, like: "some other text here highlighted text some other text here"

Thanks.

I think the best approach would be to extend Highlighter as described in the docs.

Something like:

from haystack.utils import Highlighter

class ShowMoreTextHighlighter(Highlighter):
    def find_window(self, highlight_locations):
        their_start, their_end = super(ShowMoreTextHighlighter, self).find_window(highlight_locations)
        # perform some clever operations here to find an earlier start location
        my_start = their_start/2 # or just do something simple
        return (my_start, their_end)
