This comment says it's possible by using:
{!join from=fromField to=toField fromIndex=fromCoreName}fromQuery
I tried it myself, and here's a more detailed example: Have two cores
  • brands {id,name}
  • products {id, name, brand_id}
BRANDS: {1, Apple}, {2, Samsung}, {3, HTC}
PRODUCTS: {1, iPhone, 1}, {2, iPad, 1}, {3, Galaxy S3, 2}, {4, Galaxy Note, 2}, {5, One X, 3}
http://example.com:8999/solr/brands/select?q=*:*&fq={!join from=brand_id to=id fromIndex=products}name:iPad
This translates to something like:
SELECT b.* FROM brands b
       INNER JOIN products p ON b.id=p.brand_id
       WHERE p.name="iPad";
Result will be: {id: "1", name:"Apple"}
