Chris, The limitation on huge genome map ranges is for display software (putting all those features into an image a person can understand). 500Kb is about an average viewable size, though some uses will draw on 1-10 Mb of data. I used a real-world test case that will be directly applicable to how fast biologists get to see their interesting genes. Some time maybe I'll benchmark bigger ranges. This use of Lucene for bio-data is perhaps not where can show its advantage most dramatically (as noted the SQL databases are pretty good at numeric searches and Lucene only edges them out by a nose:). It is really with the text (biology-jargon) rich literature, experimental data sets where Lucene can really show its stuff. Phrase searching of biology experimental phrases is a good example - almost impossible to do easily with SQL systems (even MySQL textsearch is weak here), and Lucene in my tests easily picks out relevavnt biology phrases. Lion Bioscience's SRS is a widely used commercial system that is text-search based, but it lacks phrase search ability.
