Key Levels

Key Levels

Using Standard Populations, a user’s database may be indexed on Person Names, Organization Names and Addresses using one of three Key Levels:
  • Standard
  • Extended
  • Limited
The choice of Key Level is passed to the SSA-NAME3 "get keys" function directly by the user’s application.

Standard

Standard is the recommended Key Level for typical applications. Its use overcomes most variations in word order, missing words and extra words.
It also maximizes the likelihood of finding candidates in cases of severe spelling error in multi-word names.
Standard is the default if no Key Level is specified.
Standard Keys or Extended Keys should be implemented if the Edit Rule Wizard is being used.

Extended

For high-risk or critical search applications, SSA-NAME3 can generate "Extended" Keys. Extended Keys extend Standard Keys by adding more keys based on token concatenation. The designer/developer should be aware that the use of Extended Keys will increase disk space requirements and result in larger candidate sets at search time. However, the intended use of Extended Keys is to improve reliability by finding matches regardless of word order variation and concatenation.
Standard Keys or Extended Keys should be implemented if the Edit Rule Wizard is being used.

Limited

If disk space is limited, SSA-NAME3 can generate "Limited" Keys. Limited Keys are a subset of Standard Keys. The designer/developer should be aware that the use of Limited Keys, while saving on disk space, may also reduce search reliability.
