Okay, after a bit of debugging and reading JIRA issues (SOLR-12074, SOLR-12632), I think this does not work because there's no terms index for point fields.
So it probably cannot work, and one would need to have a separate string field with the same values (copyField) to use the termfreq function with? Maybe this could be explained more clearly in the documentation. The reference guide just recommends using point fields instead of the deprecated trie fields, if one can accept the performance for field:value queries. It should also mention the functional differences of the field types. Maybe other features are affected as well? Oh, I just read that TermsComponent supports point fields (SOLR-11173), so maybe termfreq could be changed to support them as well? -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
