Calculates scores for documents matching a query by adding together, to a maximum of 100, the scores for the query's search elements. Following is an example query expression:
<SUM> ("computers","laptops")
If a search on "computers" generated a score of 50 and a search on "laptops" generated a score of 20, the preceding search would produce a score of 70. If a search on "computers" generated a score of 50 and a search on "laptops" generated a score of 75, the preceding search would produce a score of 100 (the maximum).
