VBA中xlPart匹配多空格分隔关键词失效问题求助

当前代码无法匹配空格分隔的多关键词，原因是Target.Find(What:=Cell)会将关键词单元格的内容当作完整字符串查找，而非拆分后匹配任意单个关键词。比如"wal otherstore"会被当作整体去Target里找，自然匹配不到包含"wal"但没有"otherstore"的文本。

修改方案 #

需要将每个关键词单元格的内容按空格拆分成单个关键词，逐个检查是否存在于Target文本中，只要有一个关键词匹配，就判定该账号关联成功。

关键修改说明 #

1. 关键词拆分：用Split(Trim(Cell.Value), " ")将空格分隔的关键词拆分成数组，同时用Trim处理首尾空格，避免空元素。
2. 逐个匹配：遍历拆分后的每个关键词，用Target.Find检查是否存在于Target文本中，找到任意一个匹配就标记为命中。
3. 避免重复：用集合的Key属性存储账号名，确保同一个账号不会因为多个关键词匹配而被重复添加，保证计数准确。
4. 空关键词处理：跳过拆分后为空的元素（比如关键词单元格有连续空格的情况），避免无效查找。
