Hoss Man commented on SOLR-9352:
--------------------------------
See linked issue for justification of this behavior.
My comments from recent mailing list thread that evidently sparked the creation
of this jira...
{noformat}
that behavior was intentionally added becaus most users kept getting
really confused by the older default behavion (which was previously a
0-length prefix against hte default search field)
https://issues.apache.org/jira/browse/SOLR-2996
if you do in fact whant a 0-length prefix query against hte default search
field...
* use the prefix parser: q={!prefix f=$df v=''}
* use an explicit field name: q=yourDefaultField:*
...if you just want all fields that contain any terms in your default
field, use the "fieldName:[* TO *]" range syntax (which should be more
efficient ... although it's possible "fieldName:*" was also optimized to
be as efficient ... i can't remember)
{noformat}
In my opinion this jira should be "Won't Fixed"

> Hi,
> I'm surprised by lucene query parser translating this query
> http://localhost:8983/solr/collection1/select?df=id&q=*
> in
> <str name="parsedquery">MatchAllDocsQuery(*:*)</str>
> I was expecting it to execute: "id:*"
> the problem seems to be in
> in o.a.s.parser.SolrQueryParserBase:
> the field is not set explicity but in the df, so getExplicitField returns null
> // called from parser
> protected Query getWildcardQuery(String field, String termStr) throws
> SyntaxError {
> checkNullField(field);
> // *:* -> MatchAllDocsQuery
> if ("*".equals(termStr)) {
> if ("*".equals(field) || getExplicitField() == null) {
> return newMatchAllDocsQuery();
> }
> }
