I have a question related to this.
when I search for wildcard "*11" IndexSearcher throws an exception

I tries "\**11" it works.
I'm guessing QueryParser actually throws an exception, not
IndexSearcher, correct? Wildcards at the beginning of a term are not
allowed by QueryParser.
Using \**11 works because the first character is literally an
asterisk, and thus is a legal expression.
I couldn't find any documentation related to this. What could be
the reason
for this?
I am using QueryParser and StandardAnalyser
And the query it generate looks like : "+orgId:9146 +isRegistered:1
+docNo:**11"
I see the issue though - by making it \** at the beginning, you've
effectively bypassed the QueryParser protection of not allowing
prefixed wildcard terms but achieved the same thing. Interesting hack!
