It looks like index-time boosting (field) is not possible since Lucene version 7.7.2 and

i was using before for another case the BoostQuery at search time for boosting and

this seems to be the only boosting option now in Lucene.

Best regards

Hi,-

i saw this in the Field class docs and i am figuring out the following note in the docs:

setBoost(float boost)
Deprecated.
Index-time boosts are deprecated, please index index-time scoring factors into a doc value field and combine them with the score at query time using eg. FunctionScoreQuery.

I appreciate this note. Is there an example about this? I wish docs would give a simple example to further help.
