Bug 23004: Missing authtype filter in auth_finder.pl

Bug 23004: Missing authtype filter in auth_finder.pl

In cataloguing, the use of tag editor opens authorities finder with a limit on specific authorities type.
This limit is missing with Elasticsearch.

This patch adds in query a "filter" on "term" which is the most performant way because there must be no ranking computed on this part.

Test plan :
1) Use Elasticsearch
2) Create an autority of type author (NP in UNIMARC) with heading "Tolkien"
3) Create an autority of type subject-author (SAUT in UNIMARC) with heading "Tolkien"
4) Create a biblio record
5) Use tag editor on a author field (700 in UNIMARC)
6) Seach for "Tolkien" in $a
without patch : you see the 2 authorities in results
with patch : you see only the correct authority in results (NP in UNIMARC)
7) Check search in authorities-home.pl is still OK
