Hoss Man commented on SOLR-11746: --------------------------------- bq. ...currently the behavior is largely non-sensical: ... Here's some examples of how solr behaves with a few "odd" queries (using the techproducts schema where "price" is a FloatPointField)... {noformat} price:fo*o - Valid, Matches no docs price:* - Valid, Matches no docs price:foo* - Error: "Can't run prefix queries on numeric field" {noformat} The combination of the last two particularly confuses me, since clearly PointField is going out of it's way to do some error validation of attempting a prefix query on a numeric field, but somehow that error handling isn't being triggered by the simplest case (empty prefix) _AND_ neither is it able to "match docs with prices" (which is what TrieFloatField would do by accident) > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
