I am getting this weird error message can not sort on multivalued field: fieldname on all the indexed fields. This is the full error message from solr
</head><body><h1>HTTP Status 400 - can not sort on multivalued field: price</h1><hr/><p><b>type</b> Status report</p><p><b>message</b>can not sort on multivalued field: price</p><p><b>description</b>The request sent by the client was syntactically incorrect (can not sort on multivalued field: price).</p><hr/><h3>GlassFish Server Open Source Edition 3.1</h3></body></html>
I am sure that my indexed field doesnt have multiValued=true set on
<field name="price" type="float" indexed="true" stored="true" multivalued="false" />
to make sure that i have added multiValued=false, but i am still getting the same error.
This is the URL request sent to solr
http://localhost:8080/apache-solr-3.1.0/select?wt=ruby&q=flat&fl=_id&sort=price+asc&limit=5&offset=0
and relevant rsolr call
res = solr.get 'select', :params => {
:q =>'flat',
:fl => "_id",
:sort=>'price asc',
'limit' => 5,
'offset' => 0
}
It all works fine if i remove the sort from the request.
Can some one help me out..
PS: I do have only one multivalued field in the document, but thats not used in the sort
Update:
Here the complete stack-trace from solr log

Update2:
As suggested by @Mateg i got the field details from the schema page. see below
Field: price
Field Type: FLOAT
Properties: Indexed, Tokenized, Stored, Multivalued, Omit Norms
Schema: Indexed, Tokenized, Stored, Multivalued, Omit Norms
Index: Indexed, Tokenized, Stored, Omit Norms
Index Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS
Query Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS
It says the price field is tokenized and multivalued. Its interesting not only this field is like that, all other field are also multivalued.
What a day , I finally found the problem after long struggle. Thanks to everyone
version number in schema file. As per the documentation default value for multi value is false from the version 1.1But i was using the old schema file with the version 1.0. So all fields are set to multiValued by default.
Every time i upgraded the solr, i just copy pasted the old schema file.
Now it works fine after changing this to the current version 1.4.
