Oracle Text to ElasticSearch

Hi,

We are currently using Oracle Text for Search (PATH_SECTION_GROUP),
Data store as XML in Oracle Database XMLTYPE Column.

Unable to Scale.

Volume is around 500 million XML doc (10KB per doc size), with plan to
ingest around 10 million xml doc's per day

XML has around 300 elements

Appreciate any advice how to move to ElasticSearch.

Thanks,
