Hoss Man created SOLR-11746:
-------------------------------
Summary: numeric fields need better error handling for
prefix/wildcard syntax -- consider uniform support for "foo:* == foo:[* TO *]"
Key: SOLR-11746
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.
