RELRANK_NTERMS

The RELRANK_NTERMS element implements the Number of Terms (Nterms) relevance ranking module.

This module assigns a score to each result record based on the number of query terms that the result record matches. For example, in a three-word query, results that match all three words are ranked above results that match only two words, which are ranked above results that match only one word.

This module applies only to search modes where the number of results can vary in how many query terms they match. These search modes include Partial, Any, AllPartial, and AllAny.
