Function queries are notoriously slow. Another way to boost by year is
with range queries:
[NOW-6MONTHS TO NOW]^5.0 ,
[NOW-1YEARS TO NOW-6MONTHS]^3.0
[NOW-2YEARS TO NOW-1YEARS]^2.0
[* TO NOW-2YEARS]^1.0
Notice that you get to have a non-linear curve when you select the
ranges by hand.
Lance, I have worked out my major issue and now have my post date in
Solr as a tdate field named "pd." I cannot however figure out how to
actually send a query with a date boost like you've mentioned above.
I'd like to embed it right into the dismax handler definition, but it
would be good to also know how to send it in a query myself. Can you help?
Are the boosts indicated above a multiplier, or an addition?
Thanks,
Shawn
