Meaning of "max clauses 1024" error

["Dave C." <da...@hotmail.com>]

Hello,

I'm curious as to the meaning of a certain exception I am receiving.
If i try a query such as "*", I get an exception which basically says there is a maximum of 1024 clauses for a BooleanQuery.  However, if I enter "*:*" it matches all documents and returns them.
Can someone explain to me what happens when the query is "*" versus a query for "*:*"?

Thanks,
David

*:* is syntactic sugar solr supports for finding all documents .... but 
i'm really suprised you get an error related to a max of 1024 clauses from 
a search for "*" .... to the best of my knowledge that has always (in 
released and unreleased versions) produced this example...

Cannot parse '*': '*' or '?' not allowed as first character in WildcardQuery

...are you sure that's waht you were searching on?
