limiting the rows returned for a query

[mike topper <mt...@riseup.net>]

Hello,

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 
q=stateid:1 countryid:1

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.

anyways hope that makes sense,

let me know!

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?)
