I have a question that I couldn't really find the answer to and dont
really know if its possible currently within solr.
I want to do a simple query to the solr index. something like
but i'm really only concerned with getting the record above and below a
certain (dynamic) recordid in the search results.
Is there a way to do this through a query or is my only option to return
all the search results and parse them to find the record id I want, and
then get the one above and below that. I'd also have to take into
account pagination and whatnot which makes it also a little bit harder
to do this way.

you have to define what "above and below" means in your context ... do you
mean assuming a sorting on some field? if so then you could
write a custom FunctionQuery that looks at the value for a given doc and
scores things based on how close their value is.
alternately you could have a custom RequestHandler that does the search,
and walks the DocList on the server side ... either way you need some
custom java code.
but i could be missing some easy solution ... it all depends on the
specifics of your problem (can you give a concrete example?)
