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 ” + fieldName + ” 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).

  try {

  throw new ParsingException(parser.getTokenLocation(); queryName + " [" + fieldName + "] " +
  "as a nested span clause can't have non-default boost value [" + clause.boost() + "]");
  } catch (UnsupportedOperationException ignored) {
  // if boost is unsupported it can't have been set


Run the Check-Up to get a customized report like this:
