Spelling Correction operates by computing alternate
spellings for user query terms, evaluating the likelihood that these
alternate spellings are the best interpretation, and then using the best
alternate spell-corrected query forms to return extra search results.
Example: A user might search for records containing the text skrts. With spelling correction enabled, the Endeca MDEX Engine will return the expected results: those containing the text skirts.
Did You Mean (DYM) functionality allows an application to
provide the user with explicit alternative suggestions for a keyword
search.
Examples #1: User searched for denms and the Endeca MDEX Engine will return the expected results those containing the text denim and also DYM suggestions for downs
Examples #2: User searched for blk and the Endeca MDEX Engine returned no results but has DYM suggestions for back, belt & black
