            Bug ID: 24372
           Summary: Elasticsearch - cannot search for titles containing a
                    colon next to a search term using the colon

           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5 - low
         Component: Searching - Elasticsearch

Using an example record in the testing DB, try searching for:
Pictura murală din nordul Moldovei: modificari estetice si restarare = Mural
painting in the north of Moldavia: aesthetic modification and restoration

In ES the search fails. If you look at the query we end up with terms like:
Moldoveimodificari AND Moldaviaaesthetic

This is because of this line in Koha/SearchEngine/Elasticsearch/QueryBuilder.pm
 935     # Remove unquoted colons that have whitespace on either side of them
 936     $term =~ s/(\:[:\s]+|[:\s]+:)$lookahead//g;


Removing colons with a space on either side, we must be careful to put that
space back:
 936     $term =~ s/(\:[:\s]+|[:\s]+:)$lookahead/ /g;
