Hoss Man updated SOLR-2996:
---------------------------
Description:
More then a few users have gotten burned by thinking that "{{\*}}" is the
appropriate syntax for "match all docs" when what it really does (unless i'm
mistaken) is create a prefix query on the default search field using a blank
string as the prefix.
since it seems very unlikely that anyone has a genuine usecase for making a
prefix query with a blank prefix, we should change the default behavior of the
LuceneQParser and EDismaxQParsers (and any other Qparsers that respect
{{\*:\*}} if i'm forgetting them) to treat this situation the same as
{{\*:\*}}. we can offer a (local)param to force the old behavior if someone
really wants it.
