First of all, just using Lucene to replace rdms is quite possible in some specific cases.
In addition to updating and string/number issues, Lucene also lacks many rdms functionalities. One of them is aggregation functions like SUM(), or "group by". Of course, in some case, you may be able to get around it by just using Lucene's existing functionalities. But you will need to worry about multi-threaded updating, Lucene index optimization, etc. Chris Lu ------------------------------ Lucene Full-Text Search on Any Database http://www.DBSight.net On 10/25/05, Daniel Naber <[EMAIL PROTECTED]> wrote: > On Dienstag 25 Oktober 2005 22:37, Sam Lee wrote: > > > Can Lucene to be used in place of mysql so that > > website visitors can input data that will in turn > > inserting row into Lucene just like mysql db? > > That's a bad idea.
