Facets values with commas not showing up

We use comma (" , " ) separated values as a delimiter between unique_id, key and value. In this case, comma is coming in the key itself.

This is the reason that facet value might not be read properly in the imports. 

There are two options to make this work: 

• Fields containing line breaks (CRLF), double quotes, and commas
  should be enclosed in double-quotes. For example:

"aaa","b CRLF

bb","ccc" CRLF

zzz,yyy,xxx

• The other option is to change the field name itself to not include comma.
