jQuery UI Autocomplete Search by multiple fields

I am using jQuery UI autocomplete and it is working fine. Below is the sample code:

<element>.autocomplete({source: availableTags,
position: {
    my: "left top",
    at: "left bottom",
    collision: "flip"
}});

})

and

availableTags = ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]

Can I add Multiple fields here? Like tags associated with value? For e.g, "java" has associated tag called "language".

How can i setup source in a way that if user search for "java" or they search "language", both should return "java"?
