Hoss Man commented on SOLR-11746:
---------------------------------
bq. IMO it should count as a bug that numeric_field:* doesn't work.
+1
I would go so far as to say thta once we "fix" this bug, we should also update
QueryEqualityTest to assert that for all indexed/docValues/trie/points
permutations of "primative" types (numbers, dates, string, boolean)
{{field:\*}} should produce an identical Query object to {{field:\[\* TO \*\]}}
-- so that whatever "optimizations" may exist (or be added in the future) in
one query parser code path, also happen for the other syntax as well.
> numeric fields need better error handling for prefix/wildcard syntax --
> consider uniform support for "foo:* == foo:[* TO *]"

> URL: https://issues.apache.org/jira/browse/SOLR-11746
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Hoss Man
>
> On the solr-user mailing list, Torsten Krah pointed out that with Trie
> numeric fields, query syntax such as {{foo_d:\*}} has been functionality
> equivilent to {{foo_d:\[\* TO \*]}} and asked why this was not also supported
> for Point based numeric fields.
> The fact that this type of syntax works (for {{indexed="true"}} Trie fields)
> appears to have been an (untested, undocumented) fluke of Trie fields given
> that they use indexed terms for the (encoded) numeric terms and inherit the
> default implementation of {{FieldType.getPrefixQuery}} which produces a
> prefix query against the {{""}} (empty string) term.
> (Note that this syntax has aparently _*never*_ worked for Trie fields with
> {{indexed="false" docValues="true"}} )
> In general, we should assess the behavior users attempt a prefix/wildcard
> syntax query against numeric fields, as currently the behavior is largely
> non-sensical: prefix/wildcard syntax frequently match no docs w/o any sort
> of error, and the aformentioned {{numeric_field:*}} behaves inconsistently
> between points/trie fields and between indexed/docValued trie fields.
