Quick newbie question

[Federico Tonioni <Fe...@isti.cnr.it>]

Hi all!
I have just a simple question

How can I retrieve all documents in an index by using QueryParser?
I thought 

Query query = QueryParser.parse("*", "contents",
                    new StandardAnalyzer());

might be the solution, but it's not:)

thanks in advance
fede

In general, you can't.  Many have used a technique of indexing a  
single field with the same value for all documents and done a query  
for field:value to find all documents.
