   Both the (documented) `example/films/films.json` and (undocumented) 
`example/films/films.xml` files work but for the (undocumented) 
`example/films/films.csv` file there's an error
   
   ```
   Caused by: org.apache.solr.common.SolrException: incorrect vector format. 
The expected format is:'[f1,f2..f3]' where each element f is a float

   i.e. probably 
https://github.com/apache/solr/blob/releases/solr/9.4.1/solr/core/src/java/org/apache/solr/util/vector/DenseVectorParser.java#L54-L57
 and perhaps it's an edge case or perhaps pipe-delimited-strings could be 
supported there too?
   
   @alessandrobenedetti @epugh WDYT? I'd be happy to create a JIRA issue for 
that if it seems like a reasonable idea.
