Erick Erickson commented on SOLR-1401:
--------------------------------------

SPRING_CLEANING_2013 JIRAS. I can freely define the ID field as text_en_splitting, index weird IDs, and get lots of documents. Seems like this is quite valid even today. Don't know how it plays with distributed indexing and doc routing though....

> over the years, have seem more then a few solr-user posts noticing odd behavior when using a uniqueKey field configured to use TextField with a non trivial analyzer ... we shouldn't error on TextField (KeyworkdTokenizer is perfectly legitimate) but we should error if that analyzer produces multiple tokens.  
> Likewise we should verify that good error messages if uniqueKey field is configured such that multivalued=true.
