RE: Forced Top Document

Yes, this will only work if the results are sorted by score
(the
default). 

One thing I thought of after I sent this out was that this
will include
the specified document even if it doesn't match your search
criteria,
which may not be what you want.

Charlie,

That's interesting. I did try something like this. Did you
try your  
query with a sorting parameter?

What I've read suggests that all the results are returned
based on  
the query specified, but then resorted as specified.
Boosting (which  
modifies the document's score) should not change the order
unless the  
results are sorted by score.

I'm going to be doing something similar, and I don't think
I'll be
sorting by score (although, that might be feasible).  In my
use-case
though, we don't want to include something unless it is
already matched
by our filters.  I'll probably end up just making two search
hits, but
it would be nice if solr could handle it for us.

This method Charlie suggested will work just fine with a
minor tweak.
For relevancy sorting

?q=foo OR (foo AND id:bar)

For nonrelevancy sorting, all you need is a multilevel sort.
Just add
a bogus field that only the important document contains.
Then sort by
bogus field in descending order before any other sorting
criteria are
applied.

Either way, the document only appears when it matches the
search
criteria, and it will always be on top.

If you use dismax, you can add the boost to the 'bq'
parameter to  
affect scoring only (will not match the doc if it wouldn't
have been  
matched anyway).
