Database Search Order

The Spectrum Enterprise Tax is able to process addresses using multiple databases at the same time. This allows you to find the best possible match from a variety of data sources and types of data (point as well as street segment data).

Spectrum Enterprise Tax processes these multiple data sources using a default search order. When the system matches an address exactly, it stops searching rather than continuing the search in additional databases. This saves on processing time. When an exact match is not found, Spectrum Enterprise Tax continues searching all of the available data sources for candidate address matches. The candidates are then scored and the highest scoring match from all of the data sources is returned as the match. If multiple candidates receive an identical score when matched to either the Points or Streets files, you have the option to set what results should be returned.

The default search order for Spectrum Enterprise Tax is:

Landmark Auxiliary file
User Auxiliary file
State-supplied file
GeoTAX Auxiliary file
Points file, if licensed
Streets file
