Thomas Mueller commented on OAK-7151:
-------------------------------------

This no longer works:

{noformat}
/jcr:root/tmp/test//element(*, nt:base)[jcr:contains(., 'hello')]/(rep:excerpt())
{noformat}

> As discovered in OAK-4401 we fallback to {{SimpleExcerptProvider}} when requesting excerpts for properties.
> The issue as highlighted in [~teofili]'s comment \[0] is that we at time of query we don't have information about which all columns/fields would be required for excerpts.
> A possible approach is that the query specified explicitly which columns would be required in facets (of course, node level excerpt would still be supported). This issue is to track that improvement.
> Note: this is *not* a substitute for OAK-4401 which is about doing saner highlighting when {{SimpleExcerptProvider}} comes into play e.g. despite this issue excerpt for non-stored fields (properties which aren't configured with {{useInExcerpt}} in the index definition}, we'd need to fallback to {{SimpleExcerptProvider}}.
