Selects documents that include at least one of the search elements you specify. Valid search elements are two or more words or phrases. Selected documents are relevance-ranked.
The ACCRUE operator scores selected documents according to the presence of each search element in the document using a "the more, the better" approach: the more search elements found in the document, the better the document’s score. Several examples of the ACCRUE operator appear in the sample outline file in the previous section, "Sample Topic Outlines."
