Why? >>>>> I could go on for days on this one but I will try to be brief. Building an XML search engine is trivial, if you ignore the context provided by XML. Onthe other hand, if you plan to make use of the contextual structure of XML, you are looking at one of the most difficult tasks one could ever encounter. When we built www.goxml.com starting in 1998, we preserved all the CDATA, the structure and the relationships between the two. The result was a true contextual search engine with an index that grew by 400% the size of each document indexed - highly undesirable. The current incarnation (GoXML v 3.01), is writen in C and C++ and uses a completely different internal mechanism for storing the information. It is no longer dependant on any third party database product as the first version was. Accordingly, we can index up to 2 terrabytes of XML data and the index grows by as small as 3/4 the size of hte original document indexed. My advice - take a look at the user interface http://goxmlsearch.xmlglobal.com/ and use that as a starting point. A lot of information on Version 2.0 is available on http://www.goxml.com Cheers and good luck!!!! Duane Nickull
