Is it possible to use elastic search on pagelist properties via custom search properties and report definition?
Yes, It’s possible
Yes, it’s supported.
@SohamM95 as @sangr2 correctly points out via our documentation, it is possible.
I will provide you with the correct documentation links for your Pega 8.8 version (as docs-previous.pega.com will be discontinued):
https://docs.pega.com/bundle/platform/page/platform/search-engine/custom-search-properties.html
it is possible to use elastic search on pagelist properties via custom search properties and report definition. You can specify these properties to include in the search index by creating a custom search property data instance. However, you should be aware that including all properties might affect performance. Also, the system does not support embedded properties in report definitions. Reports with embedded properties use database instead of Elasticsearch.
