Error on using the projection parameter - fl - in Solr 4

[samarth s <sa...@gmail.com>]

Hi all,

I am in a process of migrating my application from Solr 3.6 to Solr 4. A
query that used to work is giving an error with Solr 4.

The query looks like:
q=*:*&fl=E_abc@@xyz

The error displayed on the admin page is:
can not use FieldCache on multivalued field: E_abc

The field printed in the error has dropped the part after the character '@'.

Could not find any useful pointers on the forums, except one that has a
similar issue but while using the 'qt' parameter. Reference to this chain
is:
Subject: "multivalued filed question (FieldCache error)" on solr-user forums

Thanks for any pointers.

Thanks Erik.

Will take your advice as a long term solution. Currently working around by
using the the regex capability added in parsing the 'fl' parameter, using
'fl=E_*'

You really have a field name with '@' symbols in it? If it worked in 3.6,
it was probably not intentional, classic "undocumented behavior".

The first thing I'd try is replacing the @ with __ in my schema...
