: is there some way to change this default value (preferably from outside via : a properties file or something similar)
It's based on the FieldCache, which thinking about it a bit: the defualts come from the default values of int[], float[], etc... I seem to recall a discussion in the past about the possibility of adding an option to FieldCache to allow people to specify a default -- but it doesn't exist now. FieldCache would need to support that before FieldCache based ValueSources could support it the safe bet is to index your data with "default" options on all the fields you care about for this type of use case. if you want the "default" in function query cases but not in other cases (range queries, etc...) you'll need to fields (copyField should take care of this) -Hoss
