Java Regex如何获得模式的所有匹配出现

Question

这是字符串

abcd&fq=-(( +ExpirationDate:[* TO *]  -ExpirationDate:[2016-12-13T08:00:00Z TO *]))&fq=-SupplierId:\"systemid:1000008557\"&fq=-Id:\"systemid:1000009073\"&rows=20&arches.preview=false&sort=score desc,DefaultRelevance desc&bmf=50&wt=text";

想获得以下作为输出

fq=-(( +ExpirationDate:[* TO *]  -ExpirationDate:[2016-12-13T08:00:00Z TO *]))

fq=-Id:\"systemid:1000008557\"&fq=-Id:\"systemid:1000009073\"

尝试如下

String regex = "fq=.*&";
Pattern p = Pattern.compile(regex);
matcher = p.matcher(str);
while (matcher.find()) {
            System.out.println(matcher.group());
}

但输出为

fq=-SupplierId:\"systemid:1000008557\"&fq=-Id:\"systemid:1000009073\"&rows=20&arches.preview=false&sort=score desc,DefaultRelevance desc&bmf=50&
