: Greetings. I am using Solr 3.4.0 with tomcat 7.0.22. I've been using
: these versions successfully for a while, but on my latest project, I cannot
: sort ANY field without getting this exception:
:
: SEVERE: org.apache.solr.common.SolrException: can not sort on multivalued
...
: The thing is, I have only one multivalued field in my schema, at least, I
: thought so. I even tried sorting on id, which is the unique key, and got
: the same error. Here are the fields in my schema:
a) multiValued can be set on fieldType and is then inherited by the fields
b) Check the "version" property on your <schema/> tag. If the value is
"1.0" then all fields are assumed to be multiValued.
Here's the comment from the example schema included with Solr 3.4...
<schema name="example" version="1.4">
<!-- attribute "name" is the name of this schema and is only used for display
purposes.
Applications should change this to reflect the nature of the search
collection.
version="1.4" is Solr's version number for the schema syntax and
semantics. It should
not normally be changed by applications.
1.0: multiValued attribute did not exist, all fields are multiValued by
nature
1.1: multiValued attribute introduced, false by default
1.2: omitTermFreqAndPositions attribute introduced, true by default
except for text fields.
1.3: removed optional field compress feature
1.4: default auto-phrase (QueryParser feature) to off
