Is location 'shelving location' if so, it should say so since there are many locations it could be - branch location, owning branch location, etc.
The "location" index is derived from 952$c, "Shelving location code", so in a default setup what is actually searched is the codes from the authorized value list 'LOC'.
Changing the label to "Shelving location" sounds like a good idea, I have done a followup patch for that, will attach it in a moment.
