In 9.3.1 a single field Address Locator against our Property Appraiser database worked just fine. The PA uses a # symbol to designate a condo unit. In 10.0 Single Field Address Locator, it will not match with a condo unit unless the # sign is entered, regardless of the Spelling Sensitivity. In 9.3.1 it would match at 90% but would still find the match.
I never thought something a core as Geocoding would break in 10.0 sp1. What a disappointment 10.0 has been!
