Solr HTTP error: OK (400) {"error":{"msg":"undefined field text",&quot

Try
https://localhost:8983/solr/posts/select?q=text:coffee

If you cannot, that means your schema.xml from WPSOLR is not loaded on your index ‘posts’.

Yes its shows “undefined field text”.

But I have schema.xml file copied on server/solr/posts/conf/schema.xml.

Do I need to change anything on this?

You have to reload this index from the Solr admin.

Once after I reload like this ,

https://localhost:8983/solr/admin/cores?action=RELOAD&core=posts

I got “The schema has been upgraded to managed,? but the non-managed schema schema.xml is still loadable. PLEASE REMOVE THIS FILE.” in log.

And I am getting this in solr server,

SolrCore Initialization Failures
coreX: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher

I got this while reload https://localhost:8983/solr/admin/cores?action=RELOAD&core=posts

<response>
<lst name=”responseHeader”>
<int name=”status”>0</int>
<int name=”QTime”>429</int>
</lst>
</response>

If your Solr server is 5.x, you must use the WPSOLR 5.x configuration files.

Can you check that ?

Yes I have used the schema and solrConfig from this WPSOLR for Solr 5.x
https://wpsolr.com/releases/#1.0

Do I need make any change on schema.xml/solrconfig?

The schema has been upgraded to managed,? but the non-managed schema schema.xml is still loadable. PLEASE REMOVE THIS FILE.

This error seems to tell your solrconfig.xml is defining a managed schema, which would mean you are not using our solrconfig.xml

See https://cwiki.apache.org/confluence/display/solr/Managed+Schema+Definition+in+SolrConfig

Thanks.. I got it working by replace conf files with original .

Fine.
