The previous algorithm was a heuristic approach which looked for a term
inside a highlighted fragment. The term in the fragment was then used
again to find the matching line in the actual content. This ocassionally
gave incorrect results where whatever happened to appear to be
highlighted was also found earlier in the document written in a
different way which was not intended to be a match.

The [Elasticsearch
highlighter](
https://www.elastic.co/guide/en/elasticsearch/reference/current/highlighting.html
)
supports setting `number_of_fragments` to `0` which means that the
highlighted result will actual be the entire content itself rather than
small fragments of content. This makes it much easier to figure out the
line number since we can just loop through this to begin with and stop
as soon as we find the opening highlight tag.

This does come at the cost that all docs are returned in the highlight
section now which makes the Elasticsearch response payload approximately
twice as large but it is the only correct way to do it that I could
find.

An alternative described in [the docs](
https://www.elastic.co/guide/en/elasticsearch/reference/current/highlighting.html
)
is to use `boundary_scanner` but this requires the [Fast vector
highlighter](
https://www.elastic.co/guide/en/elasticsearch/reference/current/highlighting.html#fast-vector-highlighter
)
which in term requires us to set `offsets` for our
[`index_options`](
https://www.elastic.co/guide/en/elasticsearch/reference/current/index-options.html
)
but this will use considerably more storage so we would like to avoid
this if possible.

It's worth noting that this won't fix the fact that highlighting is not
behaving properly in the quoted examples. For that I've created
https://gitlab.com/gitlab-org/gitlab/-/issues/254941 which is explaining
a very similar problem to this.
