Summary

Current data managers support secondary and/or primary indexes on columns of relations, but indexes that contain only some of the possible values in a column can be advantageous. Partial indexes can be created using a command like "create index-type INDEX on relname (column-name) where qualification", and can be used to improve query performance. A query optimizer can use partial indexes with modest extensions, and can choose the most profitable index to use based on selectivity and other factors. Partial indexes can be correlated, and their use should be carefully considered to avoid unnecessary disk accesses.
