jQuery-ui自动完成显示重复的结果

Question

我是一个经过大量定制的jQuery-ui自动完成功能，它可以搜索标签和描述，将结果过滤到DOM中，突出显示所选单词并按任意顺序搜索多个单词。

虽然它还没有经过测试，但我觉得我几乎就在那里，但我遇到的一个问题是，如果输入标题（例如页面类别），那么它将通过_renderItem运行两次并多次显示相同的结果。

有谁知道我在这里做错了什么？

这是我的代码：

$(function() {

            var adminPages = [
                {
                    "label": "Pages",
                    "desc": "Lorem ipsum dolor sit amet",
                    "url": "/managepages.aspx"                    
                },
                {
                    "label": "Page categories",
                    "desc": "Consectetur adipiscing elit",
                    "url": "/managecategories.aspx"
                },
                {
