when using searchsuggest function, can i get the field name of suggested value??

[#1]

I want to search class code among the majors in example below.

If I type some thing 305 as searchTerm, the suggestion shows the class codes that include 305 and which field it's included.

app.searchSuggest([searchTerm], {qSearchFields: ['engineering', 'marketing', 'science','literature']} ,function(reply){

}

i checked the values inside reply ,and it has the list of values for qSuggestions but nothings inside qFieldNames.

Can anybody help me??

Thanks in advance!
