Don't think so. The boost info is encoded and stored at index time.
Boosts that you set are multiplied by lengthNorm and then stored as a
coarse-grained float in fieldNorm values. There is a utility class that
can modify them, in contrib/misc (FieldNormModifier). It sets the boost
to 1.0 and then applies a Similarity.lengthNorm based on the Similarity
implementation of your choice. This is a little round-about, but perhaps
this could work for you?
If not, you can modify norms directly using IndexReader.setNorm(...) but
you need to remember that this method uses raw byte values, that is the
result of encoding a floating point value with
Similarity.encodeNormValue(..).
