Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” + NAME + analyzer ” + analyzer + ” not found ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: query and index.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

}
 
  @Override
  protected Query doToQuery(QueryShardContext context) throws IOException {
  if (analyzer != null && context.getIndexAnalyzers().get(analyzer) == null) {
  throw new QueryShardException(context; "[" + NAME + "] analyzer [" + analyzer + "] not found");
