The Exact module provides a finer grained but more computationally expensive alternative to the Phrase module. The Exact module groups the results into three strata, based on how well they match the query string:

The Exact module is intended for use only on small text fields such as dimension values or small property values like part IDs. Do not use it with large or offline documents. Using this module in these cases results in poor performance or application failures due to request timeouts. The Phrase module, with and without approximation turned on, does similar but less sophisticated ranking that can be used as a better performance substitute.
