Solr error in CircleCI

[hectorcorrea]

CircleCI is logging a Solr error that seems to point to the way we have configured search suggestions in Solr.

Below is the error that CircleCI logs (raw log output straight from CircleCI)

If I comment the copyField directives in our schema.xml the error goes away:

  <copyField source="*_tsim" dest="suggest" />
  <copyField source="*_tesim" dest="suggest" />
  <copyField source="*_ssim" dest="suggest" />
  <copyField source="*_si" dest="suggest" />

We should review what is it in these configuration that is causing the problem.
