A feature of WordPress Core that primes the term and/or meta caches after certain queries can result in performance issues and much longer than normal transaction times.

Offload a WP_Query to Enterprise Search
When the VIP_ENABLE_VIP_SEARCH_QUERY_INTEGRATION constant is set to true, all standard front-end search queries passed with the s argument (e.g. /?s=) are automatically sent to Elasticsearch.
Optimize core queries at scale
Performance issues can be caused by core WordPress queries that perform well when a site has a small amount of data, but as the volume of site content increases the queries require a longer amount of time to execute.
Analyze a site’s server performance
Analyzing a site’s performance, and making any necessary adjustments to improve it, will help to ensure a site’s performance during unexpected high traffic situations, including unpredictable types of request spikes. It can also improve a site’s performance during normal traffic patterns, and increase resiliency during expected high traffic events.
Rate limiting in Enterprise Search
Rate limiting is a measure put in place to protect a site’s search services from spikes in requests that can cause instability. Rate limiting is likely to occur if many pages are making the same queries directly to Elasticsearch (ES) rather than making use of caching.
Index with Enterprise Search
Indexing is the process by which data is compiled and inserted into Elasticsearch. Elasticsearch (ES) is designed for quick retrieval and filtering of items in the index. To accomplish this, ES does not store the full database of a site, and the index will differ from the site’s MySQL table indexes.
Enable Enterprise Search features
Several features built into Enterprise Search can be enabled with the command wp vip-search activate-feature. Run the command with VIP-CLI, for example:
Indexing post meta
Post meta is not indexed by default. If post meta is not explicitly defined in the allow list, it will not be indexed.
Indexing post taxonomies
Similar to post types, any registered taxonomy that is public will be indexed by default.
Indexing post types
Enterprise Search automatically indexes all public post types.
