How much ram does the JVM have?

Wildcard queries are slow. Starting with '*' are even slower. If you
want all values try "field:[* TO *]". This is a range query and lets
you pick a range of values- this picks everything.

The "*:*" is not a wildcard. It is a magic syntax for "all documents"
and does not cause a search.
