Given FileA and FileB, records A1, A2, B1, B2, B3, say we get the following record pairs and weights:
A1,B1 20 XB ('the' matched record)
A1,B2 20 DB (duplicate on B)
A1,B3 15 DB (duplicate on B)
A2,B1 15 DA (duplicate on A)
If we have Geomatch only, with cut-off at 20, only A1,B1 will be accepted. Geomatch only with cut-off at 15, A1,B1 and A2,B1 both accepted.
Geomatch Multiple, with cut-off at 15 (duplicate cut-off the same), will accept A1,B1, A1,B2 and A2,B1 as links, as A1,B1 and A1,B2 have the same weight.
Geomatch Duplicate with cut-off at 15 (duplicate cut-off the same) will accept all records as matches.
I think you want Geomatch Duplicate for your project to allow any many-to-many matching above your main cut-off.
(Section 12, page 12 in your QS User Guide gives this distinction.)
