A computer-implemented method, for searching a corpus of documents having an index, includes receiving a complex query, which includes a plurality of words conjoined by operators including a root operator and at least one intermediate operator. Respective advancement potentials are assigned to the words in the complex query. A query processor applies a consultation method to the words and operators in the complex query in order to choose one of the words responsively to the advancement potentials. The query processor advances through the index in order to find a document containing the chosen one of the words, and evaluates the document to determine whether the document satisfies the complex query.
