解析错误：令牌“ATOM”必填，u'AND'在实时搜索中找到

Question

将 AND、OR、NOT 添加到搜索查询中会引发类似 Plone 4.1 中的错误：

有人可以解释一下 Plone LiveSearch 中搜索背后的逻辑是什么吗？有什么方法可以避免这种情况，或者我可以忽略日志文件中的这些消息吗？

Answer 1

忽略它们，这是 ZCTextIndex 行为。该错误仅被记录，并且查询不返回任何内容。在您的 plone 站点中的某个位置存在“word”并已编入索引，尝试在 plone 中搜索“AND word OR”之类的内容，即使“word”存在，也不会看到任何返回。尝试仅搜索“单词”，您就会看到结果。
