I ma moving to solr4.0 from beta version. There is a exception was thrown,
Caused by: org.apache.solr.common.SolrException: _version_field must exist
in schema, using indexed="true" stored="true" and multiValued="false"
(_version_ does not exist)
at
org.apache.solr.update.VersionInfo.getAndCheckVersionField(VersionInfo.java:57)
at org.apache.solr.core.SolrCore.<init>(SolrCore.java:606)

It's seem that there need a field like
<field name="_version_" type="long" indexed="true" stored="true"/>
in schema.xml. I am wonder what does this used for?
