Thanks for the response, Erick. Unfortunately, no, these scores aren’t known
at index time: they’re specific to the user doing the search, and they can
change.
Cheers,

If so, pre-compute your boost and put it in the doc at index time.
The other thing you can do is use payloads to add a float to specific
tokens and incorporate them in at scoring time. See the Solr
documentation, if you have a relatively recent one the payload support
has been built in to Solr, otherwise here's a primer:
