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.
