Briefly, this error occurs when Elasticsearch cannot find the specified analyzer in the SimpleQueryStringBuilder. Analyzers are used to break down text into tokens for indexing. The error indicates that the analyzer specified in the query does not exist. To resolve this issue, you can either create a custom analyzer with the specified name or use one of the built-in analyzers provided by Elasticsearch. Ensure that the analyzer name is spelled correctly and is case-sensitive. If you’re using a custom analyzer, make sure it’s properly defined and loaded into Elasticsearch.

Log Context

Log “[” + SimpleQueryStringBuilder.NAME + “] analyzer [” + analyzer + “] not found” class name is SimpleQueryStringBuilder.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 if (analyzer == null) {
 sqp = new SimpleQueryStringQueryParser(resolvedFieldsAndWeights; flags; newSettings; context);
 } else {
 Analyzer luceneAnalyzer = context.getIndexAnalyzers().get(analyzer);
 if (luceneAnalyzer == null) {
 throw new QueryShardException(context; "[" + SimpleQueryStringBuilder.NAME + "] analyzer [" + analyzer + "] not found");
 }
 sqp = new SimpleQueryStringQueryParser(luceneAnalyzer; resolvedFieldsAndWeights; flags; newSettings; context);
 }
 sqp.setDefaultOperator(defaultOperator.toBooleanClauseOccur());
 Query query = sqp.parse(queryText);
