weakness is the presentation: - From my understanding of the submission instructions, the main part of the paper should include all that one needs to understand the paper (even if proofs may be in supplementary material). I thus found it awkward to have a huge algorithm listing as in Alg. 2, without any accompanying text explaining it, and to have algorithms in the supplementary material without giving at least a brief idea of the algorithms in the main body of the paper. This makes it hard to read the paper, and I think it is not appropriate for publication. - Perhaps something more should be done to convince the reader that a query of the type SEARCH is feasible in some realistic scenario. One other little thing: - what is meant by "and quantities that do appear" in line 115?
