David Smiley commented on SOLR-11801:
-------------------------------------
If the point here to make it easier for Solr plugin authors (a subset of Solr
users) to customize the highlighting response then wouldn't it be simpler to
add a few protected methods to HighlightComponent and suggest it be subclassed,
instead of adding a new abstraction "HighlightCollator"? Or if the objective
is to also provide a hl.collator param with some options then I can understand
that you might want this collator thing. But I'm not sure what value there is
to your suggested hl.collator=mapmap|arrmap params... seems a matter of taste.
BTW it would be nice if the highlight component's response was restructured to
optionally allow returning richer information -- see SOLR-1954 (return char
offsets). Certainly not to be tackled in this issue but just want to share.
bq. David Smiley, you as part of SOLR-9708 deprecated some code portions and
mentioned about future restructuring. It seems the changes proposed here would
not interfere with such plans, do you agree?
Yes.

>
> The objective and use case behind the proposed changes is to be able to
> receive not the out-of-the-box highlighting map
> {code}
> {
> ...
> "highlighting" : {
> "MA147LL/A" : {
> "manu" : [
> "<em>Apple</em> Computer Inc."
> ]
> }
> }
> }
> {code}
> as illustrated in
> https://lucene.apache.org/solr/guide/7_2/highlighting.html#highlighting-in-the-query-response
> but to be able to customise the highlighting element of the query response
> to (for example) be like this
> {code}
> {
> ...
> "highlighting" : [
> {
> "id" : "MA147LL/A",
> "snippets" : {
> "manu" : [
> "<em>Apple</em> Computer Inc."
> ]
> }
> }
> ]
> }
> {code}
> where the highlighting element itself is a list and where the keys of each
> list element are 'knowable' in advance i.e. they are not 'unknowable'
> document ids.
