Nevermind, I figured it out. Excel was applying a hidden quote on the data. Thanks anyway.

I wouldn't be surprised if there's a user-error on my end but hopefully there isn't a bug. Here's the situation. I created some test data to import and one field needs to be split into a multi-valued field. This data resides within a .csv file and is structured like the following: (below are replacement field names. Also note - there are no quotes " within the data.) field1|field2|field3|field4_valueA,field4_valueB,field4_valueC http://[myserver]/solr/[my corename]/update?commit=true&separator=|&escape=\&stream.file=[location of file]&fieldnames=field1,field2,field3,field4&optimize=true&stream.contentType=application/csv&f.field4.split=true&f.field4.separator=%2C After importing the data, I see similiar results as the below for the multi-valued field , field4: <arr name="field4"> <str>field4_valueA</str> <str>field4_valueB</str> <str>field4_valueC"</str> (Why is there a trailing quote here?) </arr> I also noticed if only 1 value is being inserted into this multivalued field - there is no issue. It always happens on the last value. Thanks in advance, Cheers! Mike
