The accrue operator selects documents that contain at least one of the search items specified in the query. There must be two or more search elements. Each result is relevance-ranked. For example, the following query searches for the word “restaurant” or “deli” or both in the copy column of the blurbs table:
select t1.score, t2.copy from i_blurbs t1, blurbs t2 where t1.id=t2.id and t1.score > 35 and t1.index_any = "<accrue>(restaurant, deli)"
