: Have you tried reading existing example schemas? They show various : permutations of copy fields.
Hmm... as the example schema's have been simplified/consolidated/purged it seems we have lost the specific examples that are relevant to the users question -- the only instance of a glob'ed copyField in any of the configsets we ship is with a single destination field. And the ref guide doesn't mention globs in copyField dest either? (created SOLR-12191) Jatin: what you are asking about is 100% possible -- here's some examples from one of our test configs used specifically for testing copyField... <dynamicField name="dynamic_*" type="string" indexed="true" stored="true"/> <dynamicField name="*_dynamic" type="string" indexed="true" stored="true"/> <copyField source="*_dynamic" dest="dynamic_*"/> This ensures that any field name starting with "dynamic_" is also copied to an "equivilent" field name *ending* with "_dynamic" so "1234_dynamic" gets copied to "dynamic_1234", "foo_dynamic" gets copied to "dynamic_foo" etc... This "glob" pattern in copyFields also works even if the underlying fields are not dynamicField... <field name="sku1" type="skutype1" indexed="true" stored="true"/> <field name="sku2" type="skutype2" indexed="true" stored="true"/> <dynamicField name="*_s" type="string" indexed="true" stored="true"/> <copyField source="sku*" dest="*_s"/> so "sku1" and "sku2" will be each copied to "1_s" and "2_s" respectively ... you could also mix & match that with a <dynamicField name="sku*" ... /> if you wanted sku1 and sku2 to have special types, but some ohther more common type for other sku* fields. : Regards, : Alex : : On Thu, Apr 5, 2018, 2:54 AM jatin roy, <jatin...@live.com> wrote: : : > Any update? : > ________________________________ : > From: jatin roy : > Sent: Tuesday, April 3, 2018 12:37 PM : > To: solr-user@lucene.apache.org : > Subject: Copy field on dynamic fields? : > : > Hi, : > : > Can we create copy field on dynamic fields?
