Interp is a general-purpose module that assigns a score to each result record based on the query processing techniques used to obtain the match. Matching techniques considered include partial matching, cross-attribute matching, spelling correction, thesaurus, and stemming matching.
Specifically, the Interp module ranks results as follows:
All non-partial matches are ranked ahead of all partial matches.
Within the above strata, all single-field matches are ranked ahead of all cross-field matches.
Within the above strata, all non-spelling-corrected matches are ranked above all spelling-corrected matches.
Within the above strata, all thesaurus matches are ranked below all non-thesaurus matches.
Within the above strata, all stemming matches are ranked below all non-stemming matches.
Because the Interp module comprises the matching techniques of the Spell, Glom, Stem, and Thesaurus modules, there is no need to add them to your strategy individually.
