We couldn't find any notebook matching 'spark'
Logs Indicate this may be issue with using older version of Lucene (5.3.0)

### What type of PR is it?
Upgrades Lucene to the current latest version 8.7.0 and upgrades the deprecated methods

### Todos
[ ] Verify if Lucene handles the index upgrade seamlessly.

### What is the Jira issue?

### Questions:
* Does the licenses files need update?
* Is there breaking changes for older versions?
* Does this needs documentation?
