All of a sudden my category manager shows this in share
JavaException: org.alfresco.repo.search.impl.lucene.LuceneQueryParserException: 11230031 Request failed 500 /solr/alfresco/alfresco?wt=json&fl=DBID%2Cscore&rows=1000&df=TEXT&start=0&locale=en_US&alternativeDic=DEFAULT_DICTIONARY&fq=%7B%21afts%7DAUTHORITY_FILTER_FROM_JSON&fq=%7B%21afts%7DTENANT_FILTER_FROM_JSON
In Alfresco explorer, I get no categories showing and if I try to add a new category that has gone missing I get told that the category already exists.
I have tried rebuilding the SOLR indexes with no success
How do I fix this?
