SOLR Search - Failed to execute the [velocity] macro. Cause: [null]

Help / Discuss
#1

xwiki version 12.10.2
Search Application 12.10.2
SOLR Search Application 12.10.2
Windows Server 2012

Hello,

I’m running xwiki version 12.10.2 and our solr search stopped working. The search suggest and search bar do not work. Using the Serach Page returns the following error.

I’ve tried uninstalling SOLR and the Search Application with no luck. I’m new to XWiki and SOLR so not sure where to go from here. Any guidance would be appreciated. Thank you!

It seems your Solr instance is not initialized, you probably have some related error in the startup log.

Thanks for the reply.
I found the following in my sotmcat9-stdout log. Not sure if this is the startup log you were referring to. Looks like SOLR is unable to create or query the indexes?
