Query regarding Dynamic Fields

Hello All,


We are using dynamic fields in our collection. We want to use it in query to fetch records. Can someone please advice on it?

i.e.: q=ABC_*:"myValue"

Here "ABC_*" is dynamic field. Currently when we tried if provide field name as above it gives "org.apache.solr.search.SyntaxError". It only returns data when provide actual field name.

Thank you for any help you can offer.

Regards,
Jay Harkhani.

However, to add to Edward's message, you can with eDismax create
synthetic field names that expand to multiple fields under the covers,
using per-field 'qf' parameter.

See: https://lucene.apache.org/solr/guide/7_5/the-extended-dismax-query-parser.html#field-aliasing-using-per-field-qf-overrides
An example (1 to 1, but still):
https://github.com/arafalov/solr-indexing-book/blob/master/published/languages/conf/solrconfig.xml#L24-L55

You should provide the full name of the dynamic field in the query like
q=s_myfield:foo, for example. Solr doesn't allow field prefix queries like
q=s_*:foo.
