I'm not exactly sure what you mean by "extend existing open source projects". Elastic the company was founded by the creators of Elasticsearch and is the way that its authors and most of its contributors are rewarded with actual cash money.

I think s/he means Elastic's use of Lucene - https://lucene.apache.org/.

Elasticsearch uses Lucene for the actual inverted index DB systems. They then built a robust and updateable distributed system on top of it. By updateable, I mean that Lucene indexes are fixed at creation, and Elasticsearch coordinates multiple index versions to expose an updateable index system.

I guess it was referring to the fact ElasticSearch is build on top on Lucene

They probably meant Lucene that ES is based on.
