Match stage probabilities?

Hi

If i perform geomatch on 3 fields, EX: name, address, zipcode,

If i give probability for name as .7, address .9 and zipcode 1.0

does it mean it does exact match on zipcode and probability match on rest of the field's?

Because i am planning to do exact match on 1 field and probability match on 2 fields?

Which probability are you specifying, and where? The match weights are based upon two probabilities; you can read about the mechanisms in the user manual.

sorry, should have explained more clearly.

what i mentioned was M probabilities and u probabilites was .01. I wanted to perform geomatch duplicate on 4 fields and i want 3 out of 4 fields to be exact values and 1 field to be probabilitic match. so if i block on those 3 exact fields, will i solve this one?

Regards,

The blocking fields require an exact match - the probabilities are ignored for these. The probabilities only come into effect to ascertain whether there's enough aggregate match weight in the remaining columns to determine a match. So it appears that you are on the right track.
