>
> Lucene index can be used in order to extract _rep:excerpt_ using
> {{Highlighter}}.
> The current implementation may suffer performance issues when the result set
> of the original query contains a lot of results, each of them possibly
> containing lots of (stored) properties that get passed to the highlighter in
> order to try to extract the excerpt; such a process doesn't stop as soon as
> the first excerpt is found so that excerpt is composed using text from all
> stored properties in all results (if there's a match on the query).
> While we can accept some cost of extracting excerpt at query time (whereas it
> was generated at excerpt retrieval time before OAK-3580, e.g. via
> _row.getValue("rep:excerpt")_) , that should be bounded and mitigated as much
> as possible.
