Solr Ping query caused exception: undefined field

问题:

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 caused exception: undefined field text at org.apache.solr.handler.PingRequestHandler.handleRequestBody(PingRequestHandler.java:76) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:129) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1376) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:365) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:260) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at

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.

回答1:

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.

Add this line in your schema.xml

<field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>
