Question

Im trying to do some work on my server but running into problems. When I try to ping the server through the admin panel I get this error, which I believe might be causing the problem:

The server encountered an internal error (Ping query caused exception:
undefined field text org.apache.solr.common.SolrException: Ping query

Can anyone give me a bit of guideance as to what might be going wrong? I’m using Solr 3.6. I think it may be to do with the defined “text” in the schema.xml??

This is my schema currently: https://gist.github.com/3689621

Any help would be much appreciated.

Based on the error, I am guessing that the query that is defined in the /admin/ping requestHandler is searching against a field named text, which you do not have defined in your schema.

Here is a typical ping requestHandler section

<requestHandler name="/admin/ping" class="solr.PingRequestHandler">
  <lst name="invariants">
    <str name="q">solrpingquery</str>
  </lst>
  <lst name="defaults">
    <str name="qt">standard</str>
    <str name="echoParams">all</str>
    <str name="df">text</str>
  </lst>
</requestHandler>

Note how the <str name="df">text<str> setting. This is the default field that the ping will execute the search against. You should change this to a field that is defined in your schema, perhaps, title or description based on your schema.
