使用Suitescript 2.0，如何搜索具有特定值的子列表项的记录

var sublistFilter = search.createFilter({
    name: 'sublist.fieldname', // 替换为子列表字段的内部ID
    operator: search.Operator.IS,
    values: '特定值' // 替换为要搜索的特定值
});

var recordType = record.Type.SALES_ORDER; // 替换为要搜索的记录类型
var sublistFieldName = 'item'; // 替换为要搜索的子列表字段的内部ID
var searchValue = '特定值'; // 替换为要搜索的特定值

var searchObj = search.create({
    type: recordType
});

var sublistFilter = search.createFilter({
    name: sublistFieldName,
    operator: search.Operator.IS,
    values: searchValue
});

searchObj.filters.push(sublistFilter);

var searchResult = searchObj.run().getRange({
    start: 0,
    end: 1000 // 替换为需要获取的搜索结果数量
});

// 处理搜索结果
for (var i = 0; i < searchResult.length; i++) {
    var recordId = searchResult[i].id;
    var fieldValue = searchResult[i].getValue({
        name: sublistFieldName
    });

    // 执行相应的操作
    // ...
}
