I tested the changes on my local machine (ILIAS 10 / trunk, PHP 8.2). Some of the results/examples can be viewed in the following lines.

Creating a new Lucene index

1. create some examples in 'Customizing/global/plugins' and 'components/CAT' directories
2. create some examples in 'Services' directory
3. create some examples in 'Modules' directory
4. create Lucene index with following command:

java -jar /var/ilias/data/target/ilServer.jar /var/ilias/data/ilServer.ini createIndex ilias_0

Result:

Doing a search after creating a new Lucene index

java -jar /var/ilias/data/target/ilServer.jar /var/ilias/data/ilServer.ini search ilias_0 "ilias"

Result:

<Hits totalHits="1" maxScore="1.2719502449035645" limit="100"><Object id="1" absoluteScore="1.2719502449035645" /></Hits>

Updating the lucene index

1. created two wiki objects on my local instance
2. updated the lucene index with following command:

Result:

INFO  main (ilServer.java:189) - Finished indexing

3. Starting a new search for the newly created wiki objects with following command:

java -jar /var/ilias/data/target/ilServer.jar /var/ilias/data/ilServer.ini search ilias_0 "wiki"

Result:
