Bug 35792: Use of uninitialized value $sub6 

Test plan:

1. Apply patch
2. Rerun and make sure the error "Use of uninitialized value $sub6 in pattern match (m//) at /usr/share/koha/lib/Koha/SearchEngine/Elastricsearch.pm" is no longer present.

Initial testing done, it works well, needs an additional sign off from an external party
