Hi Rogan,
Yes, that's right. According to Thomas Berezansky, if you have other
relevancy bumps active from search.relevance_adjustment, they will be
combined, so it won't just be the activity metrics.

Am I correct in assuming that the bump amount is essentially the
weight that bump will have when adding up the total effect of the
bumps on that search?

Hi all,
MassLNC is working with our partners at MVLC to develop an
activity metric (aka popularity metric) that will allow sites to
rank more popular items a little higher in search results than
items that don't see as much activity. I've raised this idea on
the list before. Although Evergreen allows sites to adjust
relevancy based on the appearance of keywords in certain fields,
which is highly useful, our hope is that this additional
functionality will lead to further improvement when ranking
results by relevance.
As an example, if a user were conducting a keyword search on
"abraham lincoln," there are many titles in most US libraries
where the words "abraham lincoln" show up in the title. There
would be no way to tease out the titles that are getting the most
attention by readers. In fact, a title like "Team of Rivals" ranks
very low in our search results even though there is a high
likelihood it is the title the patron is seeking. By applying a
metric based on activity, we might be able to see those
more-recently popular titles floating higher in the search results
list.
I would like to share MVLC's proposal outlining the details for
implementing this project. The proposal is available at
http://masslnc.cwmars.org/node/2757. It provides a lot of
flexibility in allowing sites to define what "high activity" means
to them. Circulation activity, holds activity, total copies, and
publication age/bib record age can all be used as an activity metric.
If you have any feedback or questions, feel free to let us know.
Kathy
