Understanding Sun Master Index Configuration Options (Repository)

Phonetic Queries in a Master Index (Repository)

You can configure both basic queries and blocking queries to perform phonetic searches from the EDM. If you use a basic query, then all entered criteria must match existing records in order to return results from the search. If you use a blocking query, several queries are performed using different combinations of data until enough matching records are returned or until all defined combinations have been tried.

For example, if you use a basic query and enter first and last name, date of birth, gender, and SSN for criteria, the basic query might not return any matches if any one of those fields does not match the criteria. However, if you use a blocking query for the same example, it might search on SSN, then on first name and date of birth, and then on last name and gender. The query returns any matching records from any of the query passes.
