It appears that there is a hard limit of 24-bits or 16M for the number of
bytes to reference the terms in a single field of a single document. It
takes 1, 2, 3, 4, or 5 bytes to reference a term. If it took 4 bytes, that
would allow 16/4 or 4 million unique terms - per document. Do you have such
large documents? This appears to be a hard limit based of 24-bytes in a Java
int.
You can try facet.method=enum, but that may be too slow.
What release of Solr are you running?
