Subject Re: an "array" liked string is treated as multivalued when adding doc to solr
Date Tue, 10 Dec 2013 23:21:26 GMT
Hi Liu;

Yes. it is an expected behavior. If you send data within square brackets
Solr will behave it as a multivalued field. You can test it with this way:
if you use Solrj and use a List for a field it will be considered as
multivalued too because when you call toString() method of your List you
can see that elements are printed within square brackets. This is the
reason that a List can be used for a multivalued field.

If you explain your situation I can offer a way how to do it.
