I wanted to suggest the NeoCore XML Management Server (XMS) as well. XMS supports text searches through XPath. Since you are looking to search a significant number of documents (200,000) XMS provides the best performance. Because of our patented Digital Processing Technology (DPP), our search times remain flat regardless of the size of your database. Our web site www.neocore.com, or I can provide you with additional information.
I've a question about XPath. I already know XPath doesn't
support full-text search well, but what I need is a simple full-
text search: I've a library of XML documents, each document
is very simple, with only two elements <title> and <excerpt>.
Now I need to do full-text search in this two elements' content.
Could XPath finish this task well? If not, could you recommend
some XML search engine and XML DB software which can do
that to me? Please notice: the software should be able to
work with very large number of XM documents - up to 200,000.
