RE: Forced Top Document

Do you know which document you want at the top? If so, I
believe you
could just add an "OR" clause to your query to
boost that document very
high, such as

?q=foo OR id:bar^1000

Tried this on my installation and it did, indeed push the
document
specified to the top.

I'd love to know this, as I just got a development request
for this  
very feature. I'd rather not spend time on it if it already
exists.

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.

The typical use case, though, is for the featured document
to be on top only
for certain queries.  Like in an intranet where someone
queries 401K or
retirement or similar, you want to feature a document about
benefits that
would otherwise rank really low for that query.  I have not
be able to make
sorting strategies work very well.

Our approach has been to create a separate index of featured
items that are
tagged by the desired query. And then the results are placed
in a different
hit list as featured results (sort of like sponsored
results).

Depending on how many of these certain queries you have, it
seems like
you could still use some variation of the strategy based on
a bogus
tag sort. If you place a dynamic field for each query term
(e.g.
foo_s, bar_s, etc) relevant to a document and then detect
when one of
the special query terms is detected, you can still sort on
the
appropriate dynamic field before applying the rest of the
sort.

That's the ticket exactly, Kyle.

What I have is the ID of my document, so I indexed a dynamic
field  
with name id_*. Then I just set that field for each document
with the  
proper ID.

So for example, to pop one document to the top of the index,
i just run:

"&q=field: value; id_700390+desc, date+desc"

Works like a charm, even with multiple documents.

"&q=field: value; id_700390+desc, id_604030+desc,
date+desc"
