Limitation on schema tags in starter kit 2?

After I load the database schema, I am showed a message: Warning: number will exceed limit (the number of tags should be fewer than 500, data taken from XMark project).
And then when I query the database, I found some elements can’t be queried.
Like:
Query “/site/people” is empty, although I loaded it into the database.
Other queries like “/site/regions” are there.

I am wondering if there is any limitations on schema tags in the evaluation version? Or am I wrong or something else?
Thanks!

It is possible in the schema editor to limit the maximum number of nodes. You can set this is the schema editor, Schema menu, Set Maximum Number of Nodes before reading in the DTD.
