Let there be a set of objects, where each object is characterized by Boolean features. Let logical query or Boolean query denote a query to find objects characterized by a Boolean function by features, for example, “documents with all words ...and

Indices improve the performance of relational databases, especially on queries that return a small portion of the data (i.e., low-selectivity queries). Star joins are particularly expensive operations that commonly rely on indices for improved perfor
