Yes, "*:*" is a special feature that directly translates into a special
Lucene query feature - MatchAllDocsQuery, but the general "*:abc" syntax is
not supported.
I'm sure that at some point general "*:" support will be added to Solr, but
it is not there today - even though LucidWorks Search does in fact have it.
I'm not even sure if anybody has filed a Jira for it.

Regarding
"There is no "*:" feature to query all fields in Solr"
When I enter the dashboard -> solr/#/[core]/query
the default is "*:*"
and it brings everything.

Thanks Jack and Giovanni.
Jack:
Regarding 1.b. have vs *have* the results were identical apart from the
score.
Basically i cant do all the stuff you recommended. I want a stemmer for an
unknown search (send the query when user enters free text to a textbox ).
giovanni- regarding requestHandler test
will I need to query using /test/...?
shouldnt it be names "/test"?

Wildcard patterns on strings are literal, exact. There is no automatic
natural language processing.
You could try a regular expression match:
q=/ ha(s|ve) /
Or, just use OR:
q=*has* OR *have*
Or, use a <copyField> of the package name to a text field and than you
can use simple keywords:
q=package_name_text:(has OR have)
Is PackageName a "string" field?
Or, maybe best, use an update processor to populate a Boolean field to
indicate whether the has/have pattern is seen in the package name. A
simple
JavaScript script with a StatelessScriptUpdateProcessor could do this in
just a couple of lines and make the query much faster.
For question 1.b the two queries seem identical - was that the case?
There is no "*:" feature to query all fields in Solr - although the
LucidWorks Search query parser does support that feature.

questions :
1.a. even if i display all results, I dont get any results with "has "

1.b. what is the difference between
