$q.all and a map function are what you need here:

function getSearchData() {
    return {
        // returns a promise for an object like:
        // { abo: resultFromAbo, ser: resultFromSer, ... }
        loadDataFromUrls: function () {
            var apiList = ["abo", "ser", "vol", "con", "giv", "blo", "par"];

            return $q.all(apiList.map(function (item) {
                return $http({
                    method: 'GET',
                    url: '/api/' + item
                });
            }))
            .then(function (results) {
                var resultObj = {};
                results.forEach(function (val, i) {
                    resultObj[apiList[i]] = val.data;
                });
                return resultObj;        
            });
        }
    };
}
