Subject Re: Query time de-boost

Could you share your actual numbers and test case? IOW, the document score
without ^0.01 and with ^0.01.

Again, to repeat, the specific boost factor may be positive, but the effect
of a fractional boost is to reduce, not add, to the score, so that a score
of 0.5 boosted by 0.1 would become 0.05. IOW, it de-boosts occurrences of
the term.

The point remains that you do not need a "negative boost" to de-boost a
term.
