difficult sort
Is this possible in 1.4.1
Return a result set sorted by a field but within Categorical groups,
limited to 1 record per group
Something like:
group1
xxx (bottom of sorted field within group)
group2
xxx (bottom of sorted field within group)
etc
is the only approach to issue multiple queries and collate in the
front end app ?

Thanks for the reply Pravesh
We can't go to trunk or apply patch to production so the field
collapsing goodness is out of reach for now.
Is multiple queries the only way to go for this ?

to apply patch for 1.4.1 version, if this is what u want?

What if you were to set up a new field, which is the concatenation of your 'field' and 'category group', and then facet on that? How many combinations would we be talking about here? And - against what field(s) do you run your query?
We did something a bit similar, where we wanted an 'author' search, where 'author' is a field in our documents. We have a field set up based on 'author' to search against, as well as a field based on 'author' for faceting. We search against the author field, return 0 results but all the facet values, and then display the facet values with their counts, and when the users select one, then we issue a new query to return all documents with that author facet value.
