How to suggest similar words in autocomplete

Question

I have an input field for locations with jquery-ui-autocomplete.

You are almost there. You can use the response function (see in API) to remove the alternate spellings from the results. Also put the best spelling ("Mallorca" in this case) last. Check this out, I hope the comments are enough to get the logic. Try to type "Ma", or "Maj" and select the only option. In both cases it will display "Mallorca"

 $( function() {
    var availableTags = [      
    { value: 'Mallorca', label: 'Palma de Mallorca' },
    { value: 'Mallorca', label: 'Majorca' },
    { value: 'Mallorca', label: 'Mallorca' },
    { value: 'Madrid', label: 'Madrid' }
    ];
    $( "#tags" ).autocomplete({
      source: availableTags,      
      response: function( event, ui ) {
        var added = [];//Keep here the unique labels that are already in the list
        for(var i=ui.content.length-1;i>=0;i--){//Start a loop, itterate all items backwards
          var cur = ui.content[i].value;//Value of the item
          if($.inArray(cur,added)==-1){//If not already loaded
            added.push(cur);//Put the new item in the list
          }else{            
            ui.content.splice(i,1);//If already loaded remove it from the results
          }
        }        
      }
    });
  } );
