The alternate title (field 246) isn't enough boosted

Example : Times Literary Supplement (TLS).
https://www.swissbib.ch/Search/Results?lookfor=Times+Literary+Supplement

The record https://www.swissbib.ch/Record/272810851 which has TLS as title and Times Literary Supplement as alternate title is ranked 39th after a lot of records which are less relevant.

Currently in searchspecs we have

  DismaxFields:
    - title_short^1000                    # main title, i.e. 245 $a
    - title_alt^200
    - title^200
    - title_sub^200
    - title_old^200
    - title_new^200
  DismaxParams:
    - [pf, 'title_short^1000 callnumber_txt_mv^100']

Probably a pf (phrase field) boost for the title_alt, title, title_sub, title_old, title_new would make sense
