Wildcards at the beginning of a term are prohibited using QueryParser
( ? is kind of * ), but
WildcardQuery may use leading wildcards (at the expense of performance).
Have a look at TestQuestionmark in TestWildcard.cs

I switched to using:
Dim aQParser As QueryParser = New QueryParser("Body", New
Lucene.Net.Analysis.Standard.StandardAnalyzer())
aQParser.SetDefaultOperator(QueryParser.Operator.AND)
Dim aQuery As Query = aQParser.Parse(BodyQuery)
bInnerQuery.Add(aQuery, BooleanClause.Occur.SHOULD)
..and when I search for:
m?croscope
m??roscope
the correct "microscope" word is found; but, when I search for:
?icroscope
System.Web.Services.Protocols.SoapException: Server was unable to process

..occurs. Any idea what I can do about this?
Thank you,
