差异对谷歌的文档搜索

Question

对于某些查询与documentlist API（以及内UI）我得到这个查询不同的结果：

1. "single_word" 
2. single_word 

For example for this: 
"mody" - I receive 69 results 
mody - I receive >200 results (many of them don't contains this word) 

(This happens also for combination of words that contains this word. For example: 
**"mody" company** and **mody company** returns different results) 

这之间的区别这搜索？以及如何推荐搜索最佳精确匹配结果？我不想收到仅包含mod（例如）单词的结果。

Answer 1

“mody”只将符号与m-o-d-y这两个字符完全匹配，并在两侧留出空白。它只匹配mody。

mody匹配包含字符m-o-d-y的标记。它将匹配mymody，mody，asdfmody，modyasdf等
