The Stratify module is used to boost or bury records in the result set.

The Stratify module takes one or more EQL (Oracle Commerce Query Language) expressions and groups results into strata, based on how well they match the record search (with the Ntx parameter). Records are placed in the stratum associated with the first EQL expression they match. The first stratum is the highest ranked, the next stratum is next-highest ranked, and so forth. If an asterisk is specified instead of an EQL expression, unmatched records are placed in the corresponding stratum.

The Stratify module can also be used for record boost and bury sort operations. In this usage, you must specify Endeca.stratify as the name for the Ns parameter.

The Stratify module is the basic component of the record boost and bury feature.
