Cheers. Hi Nick. This particular issue was on a Solr 4 instance on AWS, not on the Websolr account. But I commend you taking notice and taking an interest.

Re: Error: _version_field must exist in schema
Hello!
Look at your solrconfig.xml file, you should see something like that:
updateLog
str name=dir${solr.data.dir:}/str
/updateLog
Just remove it and Solr shouldn't bother you with the version field
information. However remember that some features won't work (like the
real time get or partial documents update).
You can also add _version_ field to your schema and forget about it.
You don't need to do anything with it as it is used internally by
Solr.

Thank you. Is there any place where this is documented? It certainly
does not appear in the relevant wiki page:
http://wiki.apache.org/solr/SolrConfigXml

That is exactly my plan, but I would also like to understand more
about what is going on. I don't like cut-and-paste programming.
Thank you very much!

Re: Error: _version_field must exist in schema
I've updated the schema.xml page, see
http://wiki.apache.org/solr/SchemaXml#Recommended_fields
Care to change the schema.xml file to warn about this too and
submit a patch?
Best

Re: Error: _version_field must exist in schema
Hello! The _version_ field is needed by some of Solr 4.0 functionality like transaction log or partial documents update. If you want to use them, just update your schema.xml and put the _version_ field definition there. However if you don't want those, you can remove the transaction log configuration in your solrconfig.xml. However please remember that when using SolrCloud you'll need that field. -- Regards, Rafał Kuć Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch - ElasticSearch On a stock Solr 4 install, I can run the server fine if I don't change any config files. When I replace the example solr/collection1/conf/schema.xml I get the following error: collection1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Unable to use updateLog: _version_field must exist in schema, using indexed=true stored=true and multiValued=false (_version_ does not exist) Here is the replacement schema: ?xml version=1.0 encoding=UTF-8? schema name=discoapiRecent version=0.3 types fieldType name=string class=solr.StrField omitNorms=true/ /types fields field name=id type=string stored=true multiValued=false indexed=true required=true/ field name=text type=string stored=true multiValued=false indexed=true/ /fields defaultSearchFieldtext/defaultSearchField solrQueryParser defaultOperator=AND/ uniqueKeyid/uniqueKey /schema I see that the original schema.xml had a _version_ field, but how does Solr know that? I did remove the original index thinking that maybe the extant documents were crying for the _version_ field, but removing that index did not help. Grepping for _version_ doesn't show it existing anywhere else in the collection1 index: ~/apache-solr-4.0.0/example$ grep -ir _version_ * multicore/core1/conf/schema.xml: field name=_version_ type=long indexed=true stored=true/ multicore/core0/conf/schema.xml: field name=_version_ type=long indexed=true stored=true/ solr/collection1/conf/schema.xml.ORIGINAL: trailing underscores (e.g. _version_) are reserved. solr/collection1/conf/schema.xml.ORIGINAL: field name=_version_ type=long indexed=true stored=true/ Where might the problem lie? And other than the index and schema.xml (and possibly solrconfig.xml) what else should I purge to get a clean index? Thanks.
