Perhaps the Lucene QueryParser should throw an exception then. Currently 1.4.3 accepts the expression as is without grumbling...
Several minor QueryParser weirdnesses like this have turned up recently. Sure enough, that is an odd one. It parses into a PrefixQuery for "fish*" and the ~ is dropped. I consider this a bug as this should really be a parse exception. I've just filed this as a bug:

Thanks, Erik.
If you're looking for an XML DB for managing and querying large persistent data volumes, Nux/Saxon will disappoint you.
I want to store at least several hundred MB up to gigabytes and have this queryable with XQuery.
With some luck it might comfortably fit into a (compressed) main memory cache.
We previously used Tamino with XPath, but our XML is not well enough normalized to make this very feasible to query. eXist, last I toyed with it, only scaled to 50MB.
Ok, so Nux/Saxon is out for our uses. Any recommendations though?
I can't recommend any product in particular. There's a comprehensive list of impls at http://www.w3.org/XML/Query
Could you briefly summarize the key usecase and an example query? If history is any indicator, then within 2-3 years the big relational DBMS vendors will have caught up with XQuery/XML extensions and eat the little special-purpose XML DB vendors for lunch - just like they did with OODBMS.
Wolfgang.
