Abstract

Official abstract text for this publication.

Methods and apparatus are described herein for performing AND/OR searching using multiple keywords. A query is received at a first node in a network having multiple keywords. The first node determines a set of documents matching a first of the multiple keywords, and computes an ideal Bloom filter representing those keywords. The first node sends the query and the Bloom filter to a second node, which determines its search results for a second of the multiple keywords in accordance with the Bloom filter.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of searching in an overlay network, comprising: receiving a query at a first node in a distributed network from a querying node, wherein the query includes a first keyword and a second keyword; finding a first set of a first number of documents that contain the first keyword; computing an optimal first Bloom filter length and a corresponding first number of hash functions as a function of the first number of documents in the first set; determi…
