When querying Index Server catalogues, I have found that in phrase queries the special characters are all treated the same, just as word separators. For example, searching for "(75)" will return all the documents containing number 75, not only those containing (75). And it looks like there is no way around it. But my customer complains that in the Windows Explorer searches he can get the exact phrase "(17)" only, and in our .asp application that uses Index Server we can not get the same results.
Does anybody know is it possible to search for those special characters (like ()[]{}.,;:!? etc.) at all, is there a way to resolve this problem, how does search-engine in windows resolve it?
