There are examples of both synonym handling and hierarchical folder-
like handling using Lucene in "Lucene in Action". The code is
available from <http://www.lucenebook.com>, as well as couple of
sample chapters.
The material there would be a good starting point for future
discussions.

I have a similar request. Does anyone know if Lucene is capable of
implementing polyheirarchical taxonomies?

You tried to parse the string "OR" as a query. AND, OR and NOT are
treated as boolean operators by the query parser, and a query that
match the operator is expected.
<http://lucene.apache.org/java/docs/queryparsersyntax.html>:
Boolean operators allow terms to be combined through logic operators.
Lucene supports AND, "+", OR, NOT and "-" as Boolean operators(Note:
Boolean operators must be ALL CAPS).
If your index is case sensitive, what if you type "OR" (with quotes)
instead?
If you index is not case sensitve, use "or" (without quotes) instead.
