Luca Cavanna commented on LUCENE-4906:
--------------------------------------
I see! If you couldn't make it how can I make it? :)
But the idea is that you could have some kind of object as output instead of a
string, like for example an array of tokens plus maybe some more information?
It would avoid to parse again the string output and somehow re-analyze the text
as needed to have a snippet that we could provide as output directly?
> PostingsHighlighter's PassageFormatter should allow for rendering to
> arbitrary objects

> For example, in a server, I may want to render the highlight result to
> JsonObject to send back to the front-end. Today since we render to string, I
> have to render to JSON string and then re-parse to JsonObject, which is
> inefficient...
> Or, if (Rob's idea:) we make a query that's like MoreLikeThis but it pulls
> terms from snippets instead, so you get proximity-influenced salient/expanded
> terms, then perhaps that renders to just an array of tokens or fragments or
> something from each snippet.
