I've not encountered the !ENTITY syntax or used more than one synonym
file.  I'll have to take your word for it that this works.

When you update a config resource, you must reload or restart for it to
take effect.  If the resource is used in index analysis, you must
reindex after reloading.  Resources used in query analysis will take
effect immediately.

With SolrCloud, you should reload the entire collection (with the
Collections API), not just a core (with the CoreAdmin API).

I don't know what you mean by "floating results" above.

Thanks,
Shawn
