Re: of^1 illegal?

Dan,

Does your Analyzer use a StopFilter? If you're using the StandardAnalyzer, for example, "of" is on its list of words to filter (via a StopFilter instance). If the single term in a query is filtered out, you're "doing" an empty query, which could cause trouble not unlike that which you report.

Hope it helps,
Steve
