Location City synonym support?
I have created the related feature request here.


  If this feature is not yet available in the location module, I could
  maybe use Views, create the indexed synonyms as taxonomy terms
  vocabulary and term reference field Content: Location Synonyms,
  modify the view's Global: combine filters filter setting Choose
  fields to combine for filtering as Location: City and Content:
  Location Synonyms? This would require tagging each node location
  synonyms manually or would require setting up a Rule (using Rules
  contrib module) that would add these synonyms automatically depending
  on the Location: City selected. The standard Drupal search would
  index these tags.
  
  It would be better to have it either inside the Location module or as
  an additional contributed helper module.


There is also a contributed module Location Taxonomize that might help in achieving this.
