Thanks for the quick response!
I am now able to retrieve excerpts in one query for both content and
properties.
According to http://issues.apache.org/jira/browse/JCR-920 it looks
like it should work for properties (and it sort of does!)
The only thing I have to figure out is how to only show the
highlighted bit and the content around it for that specific property.
This will probably need a custom excerpt provider.
Thanks for the help!

I am trying to do a basic search query on the entire repository
that returns
any node that has a sling:resourceType property and that has a
property/content that matches a search string.
If there is a match I need to get all the properties of that node
and an
excerpt of the matched string.
I have the following xpath query who returns the correct nodes:
//*...@sling:resourceType and (jcr:contains(jcr:content,'*test*') or
jcr:contains(.,'*test*'))]
This query gives me the parent of the jcr:content node and all the
properties on it, which is exactly what I want.
Now, I thought I could get the excerpts out of the results by
appending
/rep:excerpt(.) like so:
//*...@sling:resourceType and (jcr:contains(jcr:content,'*test*') or
jcr:contains(.,'*test*'))]/rep:excerpt(.)
But this doesn't give my a usable excerpt.
I guess the excerpt is only useful when done on the jcr:content node.
So I think this query should do the trick:
//*...@sling:resourceType and (jcr:contains(jcr:content,'test') or
jcr:contains(.,'test'))]/rep:excerpt()
and then you'd call the rep:excerpt() with the jcr:content as
parameter:
Row row = ...
Value excerpt = row.getValue("rep:excerpt(jcr:content)");
In this case you could also switch between the excerpt from a
jcr:content subnode or the node itself, depending on what exists.
Note that I also changed "*test*" to "test" as that should give the
same results. jcr:contains does a full text search, not an exact
comparison, hence word stemming etc. all take place.
Another problem I'm facing with excerpts is when I try to get an
excerpt out
of a property/jcr:content with no (or almost none) content around the
highlighted word/phrase.
It seems to fill up the space by taking other property values of
the node.
You can have a custom excerpt provider:
