Steve Rowe commented on SOLR-3798: ---------------------------------- After [chatting with Hoss on #lucene-dev IRC|http://colabti.org/irclogger/irclogger_log/lucene-dev?date=2013-03-01#l9], I understand copyFields a little better. Hoss argued that "undeclared explicit field" is an inaccurate description of the "third kind of thing" I was referring to, and I agree. A hopefully better characterization - something like this should be on the wiki: {panel} {{<copyField>}} source or dest values can be either field names or dynamic field references. A dynamic field reference is either an exact {{<dynamicField>}} name, or a pattern that accepts a subset of the language accepted by the pattern for a referenced dynamic field. Subset pattern syntax is the same as that for dynamic field names (*"\*string"* or *"string\*"*), with the additional possibility of excluding the asterisk (*"string"*). A {{<copyField> *source*}} subset pattern operates as a filter: instead of triggering a field copy for all field names matched by the referenced dynamic field pattern, only those that match the subset pattern will trigger a field copy. A {{<copyField> *dest*}} subset pattern operates in two ways: the target field's type is drawn from the referenced {{<dynamicField>}}; and the target field name is generated using the subset pattern as a template, unless the subset pattern excludes the asterisk, in which case the subset pattern itself becomes the target field name. {panel} > copyField logic in LukeRequestHandler is primitive, doesn't work well with > dynamicFields > ---------------------------------------------------------------------------------------- > > Key: SOLR-3798 > URL: https://issues.apache.org/jira/browse/SOLR-3798 > Project: Solr > Issue Type: Bug > Reporter: Hoss Man > Attachments: SOLR-3798.patch > > > looking into SOLR-3795 i realized there is a much bigger problem with how > LukeRequestHandler tries to get copyfield info for fields and dynamicFields > the same way, and it just doesn't work. > see the patch in SOLR-3795 for a commented out example of a test that still > fails (ie: trying to get the "copySource" info for a dynamicField) -- This message is automatically generated by JIRA.
