Re: "Tree" Data Structure Access using Google!

In fact we don't need a search engine to support the wildcard search
'*'. We just let the search engine index such "child declaration" web
pages / usenet messages:

/* BEGIN OF EXAMPLE CHILD DECLARATION
Parent Path: YaoZiyuanTree MajorTopic1 EndOfPath
Parent Path MD5: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Child Node Name Declared: MinorTopic3
/* END OF EXAMPLE CHILD DECLARATION

When expanding a parent node, we just search the search engine for the
parent node MD5 string and the exact phrase "Child Node Name Declared",
then we're supposed to get all pages that declare the immediate
children nodes of the parent path.
