The other options is to use query field alias: https://lucene.apache.org/solr/guide/8_1/the-extended-dismax-query-parser.html#field-aliasing-using-per-field-qf-overrides (example: https://github.com/arafalov/solr-indexing-book/blob/master/published/languages/conf/solrconfig.xml#L20 ). This still does not allow wildcards (I think, check!), but at least it allows to isolate field names as a reference in a separate variable. And you can update that variable using Request Parameter API: https://lucene.apache.org/solr/guide/8_1/request-parameters-api.html#request-parameters-api
You can periodically get the list of all fields, using Luke endpoint. I don't remember if/where it is documented, but you can examine the traffic between Admin UI (Analysis or Schema screen) and backend to see how it works. You may even have a custom postCommit listener defined that could check the current list of dynamic fields and write appropriate mapping: https://lucene.apache.org/solr/guide/8_1/updatehandlers-in-solrconfig.html#event-listeners Regards, Alex. P.s. If you use copyField and the target does not store content, just index - then the overhead is not too bad. And if your original fields are store-only (because they are never searched directly) and the copyField target is index-only, then there is no extra overhead.
