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.
