Bug 23521: (follow-up) Add quotes

Bug 23521: (follow-up) Add quotes

Not only should terms from facets/limits be grouped, but order should probably matter
We build a different facet for "Dillinger Girl" or "Girl Dillinger"

The parens are possibly overkill now, but I think it makes it very clear and does not hurt

To test:
1 - Follow original plan
2 - Create a new record with 'Girl Dillinger' as author
3 - Search for 'Dill*'
4 - You get all three records (and maybe others that match)
5 - Limit by 'Girl Dillinger' - you get two records
6 - Same for 'Dillinger Girl'
7 - Apply patch
8 - Limits/facets for 'Dillinger Girl' and 'Girl Dillinger' now match a isngle record
