[Weiming]I'v seen the difference. What you refered here as content based
searching actually in my slides still belongs to the index-based path. In your
example of NOP attributes, you only have one level of table, when you put the
second level of table (that is, the Datatable in the NOP LFB you mentioned,
which sub field is another table), you will see that anything is based on what
you mean content based searching (which actually isn't content based).  Pls read
other part of my slides where I think content based searching is quite different
thing, something like:

Path = {AttrID1.f1= = vf1} && {AttrID1.f1.g1 = = vg1}

where you can see the difference is, in this path, there is no index, instead
there are values for terminal nodes. Do you think a path can include values? I
think no, therefore, my opinion is that the path except the attribute ID part
should be inside the 'Data' field.

Anyway, I think what you mean content based searching is different from what I
mean, and you actually still have not mentioned content based searching in your
example.

Actually I have had a private discusion with Joel on content searching. The
slides are actually some topic we discussed, therefore I think it maybe worth to
present it to all others.

Cheers,
Weiming
