I implemented the date boosting function outline here, placed into the
boost parameter in the request handler:
http://wiki.apache.org/solr/FunctionQuery#Date_Boosting
Today it was reported to me that this boosting is producing terrible
results. A close look at the description reveals that this isn't so
much a boost on new content as it is a negative boost on old content.
This isn't what I want.
What I need to have happen is that content added today gets a small (and
easily configurable) boost, content added yesterday gets a slightly
smaller boost, tapering down to approximately two to four weeks in the
past, at which point there would be no boost at all. A document that's
a month old would have the same boost (none) as a document that's 50
years old.
Can someone figure out the formula for this?
Thanks,
Shawn
