Two easy questions...
Hi,
I am new to solr & have two questions -
1. how do i get an excerpt for a huge content field (would love to show
google like excerpts, where word searched for is highlighted)
2. If i have a field - A, is it possible to get top results with only
unique values for this field in a page...?
Thanks,
Chris

For highlighting you can read here:

For field collapsing you can read here:

This is possible using the highlighting component (search 'solr
highlighting' and you'll find it.

I think what you're asking is to only show one document for each value
of your field? If this is the case, then 'field collapsing' aka 'result
grouping' should be able to get you there. You group on your field, and
only show on value per group.
Sorry I can't give you more specifics right now, but google with the
above keywords should get you there.
