The catalog's sophisticated relevance ranking algorithm is a 'trade secret' of the software developers, so we are unable to explain exactly how it works. However, it usually gives priority to "exact title" matches on your search keywords.
For instance: a search for "practical grammar" will return items with the exact title "practical grammar" at the top. A search for "the practical grammar" will return almost identical results, but with priority given to titles with "the" in them.
