advancedOptions

Key-value pairs to specify advanced configuration options. The following key-value pairs are supported:

"rest.action.multi.allow_explicit_index": "true" | "false" - Note the use of a string rather than a boolean. Specifies whether explicit references to indexes are allowed inside the body of HTTP requests. If you want to configure access policies for domain sub-resources, such as specific indexes and domain APIs, you must disable this property. Default is true.
"indices.fielddata.cache.size": "80" - Note the use of a string rather than a boolean. Specifies the percentage of heap space allocated to field data. Default is unbounded.
"indices.query.bool.max_clause_count": "1024" - Note the use of a string rather than a boolean. Specifies the maximum number of clauses allowed in a Lucene boolean query. Default is 1,024. Queries with more than the permitted number of clauses result in a TooManyClauses error.
"override_main_response_version": "true" | "false" - Note the use of a string rather than a boolean. Specifies whether the domain reports its version as 7.10 to allow Elasticsearch OSS clients and plugins to continue working with it. Default is false when creating a domain and true when upgrading a domain.
