Alan Woodward commented on SOLR-10155:
--------------------------------------
+1, regex matching on numeric facets doesn't really make sense
> Clarify logic for term filters on numeric types
> -----------------------------------------------
>
> Key: SOLR-10155
> URL: https://issues.apache.org/jira/browse/SOLR-10155
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: faceting
> Affects Versions: 6.4.1
> Reporter: Gus Heck
> Priority: Minor
> Attachments: SOLR-10155.patch
>
>
> The following code has been found to be confusing to multiple folks working
> in SimpleFacets.java (see SOLR-10132)
> {code}
> if (termFilter != null) {
> // TODO: understand this logic... what is the case for
> supporting an empty string
> // for contains on numeric facets? What does that achieve?
> // The exception message is misleading in the case of an
> excludeTerms filter in any case...
> // Also maybe vulnerable to NPE on isEmpty test?
> final boolean supportedOperation = (termFilter instanceof
> SubstringBytesRefFilter) && ((SubstringBytesRefFilter)
> termFilter).substring().isEmpty();
> if (!supportedOperation) {
> throw new SolrException(ErrorCode.BAD_REQUEST,
> FacetParams.FACET_CONTAINS + " is not supported on numeric types");
> }
> }
> {code}
> This is found around line 482 or so. The comment in the code above is mine,
> and won't be found in the codebase. This ticket can be resolved by
> eliminating the complex check and just denying all termFilters with a better
> exception message not specific to contains filters (and perhaps consolidated
> with the proceeding check for about prefix filters?), or adding a comment to
> the code base explaining why we need to allow a term filter with an empty,
> non-null string to be processed, and why this isn't an NPE waiting to happen.
