Hi, I am looking for some product that can store a "knowledge database". Open-source or commercial (the cheaper, the better), Zope or otherwise. I simply need to store text files, and make them searchable. I know that ZCatalog can kind of do the job, I used it a few years ago, but back then the search features were kind of limited (for instance, two-word search was hard to implement, like when searching for "correlation matrix": you don't want files that contain "correlation" and/or "matrix", you want files that contains the two words consecutively. Also, back then, ZCatalog did not have "and", "or" logical operators.) I don't know whether it's been improved recently. (I know search engine is no easy matter.) Ideally the product should allow some sort of failure report (when some user looks up for certain keywords and couldn't find anything), and also some basic statistics, so that a human editor could improve the hit scores, say, once a day or once a week. Anyway, I am looking for something that is not 100% automated: it would be great if some human editor assistance can be incorporated to make the knowledge database's output more reasonable. I'd appreciate any pointers. regards, Hung Jung __________________________________________________ Do You Yahoo!? Sign up for SBC Yahoo! Dial - First Month Free http://sbc.yahoo.com
