Given that many queries in genomics, proteomics or metabolomics involve these kinds of comprehensive searches, we have developed a web-based tool called <strong>PolySearch</strong>. PolySearch supports more than 50 different classes of queries against nearly a dozen different types of text, scientific abstract or bioinformatic databases. The typical query supported by PolySearch is "Given X, find all Y's" where X or Y can be diseases, tissues, cell compartments, gene/protein names, SNPs, mutations, drugs and metabolites. PolySearch also exploits a variety of techniques in text mining and information retrieval to identify, highlight and rank informative abstracts, paragraphs or sentences.</p>
