My guess is you want to look into the Scorer implementations. I am
not sure Lucene's term vector storage is needed, you could just store
the terms as they always are and implement your own Query/Weigh/Scorer
combo that ignores TF and uses your new approach.
See http://lucene.apache.org/java/docs/scoring.html for more info.
Otherwise, if you really want to use the TermVectors just for scoring,
you may find the TermVectorMapper addition on the trunk to be useful
for extracting the info you want.
Might be able to offer more suggestions if you can provide more detail
about what you are trying to do.

Hi:
I want to build a custom termfreq vector an add it to the field to
store it
to the index.
I want to use lucene for research, I'm thinking to make some
experimentation
so I need to store a term vector in a field in the index not based
in the
frecuency of the term in the document instead of I want to use another
measure to get ranking improvements.
How can I do that. Is that posible with lucene ?
I will appreciate your help.
Greetings
