我正在尝试使用API自动进行Scopus搜索，以便我们可以更轻松地跟踪与联合国可持续发展目标相关的出版物。然而，我无法正确理解每个SDG的搜索字符串都是长而复杂的。此处记录了每个SDG的搜索字符串：https://data.mendeley.com/datasets/87txkw7khs/1#file-71334e20-2e74-4557-9002-0b8d2b28103e
我正在测试SDG2，其中有一个字符串，看起来像这样：
TITLE-ABS-KEY ( ( {land tenure rights} OR ( smallholder AND ( farm OR forestry OR pastoral OR agriculture OR fishery OR {food producer} OR {food producers} ) ) OR malnourish* OR malnutrition OR undernourish* OR {undernutrition} OR {agricultural production} OR {agricultural productivity} OR {agricultural practices} OR {agricultural management} OR {food production} OR {food productivity} OR {food security} OR {food insecurity} OR {land right} OR {land rights} OR {land reform} OR {land reforms} OR {resilient agricultural practices} OR ( agriculture AND potassium ) OR fertili?er OR {food nutrition improvement} OR {hidden hunger} OR {genetically modified food} OR ( gmo AND food ) OR {agroforestry practices} OR {agroforestry management} OR {agricultural innovation} OR ( {food security} AND {genetic diversity} ) OR ( {food market} AND ( restriction OR tariff OR access OR {north south divide} OR {development governance} ) ) OR {food governance} OR {food supply chain} OR {food value chain} OR {food commodity market} AND NOT {disease} ) )
花括号根本不适用于API交互式工具(即使是单个项目(，所以我尝试了这个版本的查询：
TITLE-ABS-KEY(("land tenure rights" OR (smallholder AND (farm OR forestry OR pastoral OR agriculture OR fishery OR "food producer" OR "food producers") ) OR malnourish* OR malnutrition OR undernourish* OR "undernutrition" OR "agricultural production" OR "agricultural productivity" OR "agricultural practices" OR "agricultural management" OR "food production" OR "food productivity" OR "food security" OR "food insecurity" OR "land right" OR "land rights" OR "land reform" OR "land reforms" OR "resilient agricultural practices" OR (agriculture AND potassium) OR fertili?er OR "food nutrition improvement" OR "hidden hunger" OR "genetically modified food" OR (gmo AND food) OR "agroforestry practices" OR "agroforestry management" OR "agricultural innovation" OR ("food security" AND "genetic diversity") OR ("food market" AND (restriction OR tariff OR access OR "north south divide" OR "development governance")) OR "food governance" OR "food supply chain" OR "food value chain" OR "food commodity market" AND NOT "disease"))

结果是服务错误：；"服务错误"：｛"status"：｛"statusCode"："INVALID_INPUT"，"statusText"："翻译查询时出错">
我是不是错过了什么？还是API不支持这么长时间的查询？
它只对我有用一次。。。
- 。。。将开头大括号
{替换为%7B，并且 - 闭合大括号CCD_ 6与CCD_
(另请参阅URL中大括号的解释。(
