[TECHNICAL-SUPPORT | May 5]  LPS-46366 Search portlet does not find DDL records that are on a different site and search scope is set to "Everything"

https://issues.liferay.com/browse/LPS-46366

Commit messages reworded to use "LPS".
I also split your original 2nd commit.

Regarding the new constants: I know it's not an existing pattern right now, but it's a bit ugly to use those hard-coded strings in all of our indexers. IMHO, it'd be worth to create a "Trivial" Story & refactor all indexers to use constants. I hope you share my idea. :-)

Anyway, thanks for fixing this issue for us! ;-)

Tibor
