C4::Search->FindDuplicate joins title and author using 'and'
(lowercase). When this query is passed on to ElasticSearch, it
interprets the lowercase 'and' as a term to search for, because the
operator has to be in uppercases ('AND').
Test plan:
* Reproduce the bug:
- Set SearchEngine to ElasticSearch (and make sure you have the data
indexed etc)
- Find an existing book, note the title (245a) and the author (100a)
- Create a new book (Cataloging -> New Record)
- Fill in the same title and author using the same data as in an
existing book (and any other fields that might be required)
- Click "save"
=> A new book will be created, the Duplicate Finder has failed
* Apply the patch
* Check if it's working now:
- Create a new book (Cataloging -> New Record)
- Fill in the same title and author using the same data as in an
existing book (and any other fields that might be required)
- Click "save"
- The DuplicateFinder should now report the already exising book
Maybe we should also check if Zebra does not have any problems with the
uppercase 'AND'? In that case, repeat the above steps, but set
SearchEngine to Zebra :-)
