Re: qf in conjunction with boost
On further reading it seems that maybe
=map(popularity_d,0,0,1) might work

Re: qf in conjunction with boost
Thanks for you reply.
The problem I ran into with using the boost parameter was that not all of my
documents have the boosting field and those were coming back with a score of
zero. I tried setting a default for that field but it didn’t help. I found
somewhere that using the boost parser with a map function would get me around
that and it seemed to until I noticed that the qf parameter was being ignored.
Maybe I can use bf instead.

qf is a parameter for the dismax and edismax query parsers, but your
query has changed to the boost query parser. It is very unlikely that
the boost parser uses the qf parameter.
It looks like using edismax with its "boost" parameter MIGHT be what you
are after:
https://lucene.apache.org/solr/guide/8_1/the-extended-dismax-query-parser.html
The edismax parser also supports the bq and bf parameters from the
dismax parser:

No responses yet, is my question unclear or is this not possible?

qf in conjunction with boost
Hello,
I have been using the following to boost based on field content.
qf=title^5 description^5 _text_
And now I want to include additional boosting based on a popularity score
include with some documents. I’ve done this as follows
q={!boost b=map(popularity_d,0,0,1)}
However now it seems that the score is the same regardless of whether qf is
included or not - this renders qf irrelevant to my query.
Can I do both of these boostings? A multiplicative boost on the fields is
acceptable if that’s possible and simplifies an answer.
