Determining the Weight Thresholds
The default match configuration file, matchConfigFile.cfg, defines several rules that you can customize for the type of data being processed. Each rule is identified by a match type in the first column of each row. This value identifies the type of matching to perform to the match engine. In a master index application, the match type is entered for each field in the match string section of mefa.xml.
The match configuration Master Index Match Enginefile appears under the Match Engine node of the master index project. For more information about the comparison functions used for each match type and how the weights are tuned, see Customizing the Match Configuration and Master Index Match Engine Comparison Functions.
The following four tables list match types that are typically used in processing different data types, including:
The following match types are designed for matching on person data.
Table 12 Person Data Match Types
|
The following match types are designed for matching on address data.
Table 13 Address Match Types
|
The following match types are designed for matching on business names.
Table 14 Business Name Match Types

Miscellaneous match types provide additional logic for matching on a variety of data types, such as date, numeric, string, and character fields.
