Hi ,
	I think it doesn't have anything to do with number of characters
with a wildcard. Because 'z*' works and 'a*' does not.
Does lucene have a limitation on the number of hits fetched ?
The error that I get is=0D

Is there a limitation in Lucene when it comes to wildcard search ?=0D
Is it a problem if we use less than 3 characters along with a
wildcard(*).
Gives me error if I try using 45* , *34 , *3 ..etc .=0D
Too Many Clauses Error
Doesn't happen if '?' is used instead of '*'.
The intriguing thing is , that it is not consistent . 00* doesn't fail.
Am I missing something ?
