In the standard query parser, this means "remove all entries in which field_a = 54".
> bq=-field_a:54^10000 Generally speaking, by convention boosts in Lucene have unity at 1.0, not 0.0. So, a "negative boost" is usually done with boosts between 0 and 1. For this case, maybe a boost of 0.00001 is what you want?
