Troubleshoot Elasticsearch Feed Ingestion Issues

In some cases, complex search queries cause Elasticsearch to fail on stackoverflow.

We recommend that you use the following search query syntax:

field:(a,b,c …)

Workaround

To fix this issue, you can increase the maximum clause count and the maximum total field count in the

elasticsearch.yml

file.

Maximum clause count
Elasticsearch Version	Key	Value
6.0 and later	index.query.bool.max_clause_count	A number larger than the default of 1,024.
5.x and earlier	indeces.query.bool.max_clause_count	A number larger than the default of 1,024.

The maximum total field count includes nested fields. The default value is 1,000.

Maximum total field count
Key	Value
index.mapping.total_fields.limit	A number larger than the default of 1,000.
