搜索符号在编程中很常见，特别是在您不熟悉某种语言时。
例如，我在Python中有一个有关 ::运算符的 question，这是不可搜索的。寻找此类或 Object [](对象数组)之类的东西的人找不到他们想要的东西。

为什么搜索引擎似乎完全忽略符号？他们就像其他任何角色一样。我明白为什么
与单词相比，很难从符号中提取语义(例如:搜索引擎可以找出“查找”，“查找”，“找到”都是相关的，即使不是同一单词)，
但是真的很难找到它们吗？

我还可以理解为什么在日常使用中您希望忽略符号，但是这样做会有多困难
使其明确寻找内容(例如: "::"将搜索::)

Google ignores some punctuation and special characters, including ! ?

, . ; [ ] @ / # < > .

Because punctuation is typically not as important as the text around it, Google ignores most punctuation in your search terms. There are exceptions, e.g., C++ and $99. Mathematical symbols, such as /, <, and >, are not ignored by Google's calculator.

[ Dr. Ruth ] returns the same results as [ Dr Ruth ]

What if you're seeking information that includes punctuation that Google ignores, e.g., an email address? Just enter the whole thing including the punctuation.

Be aware that web pages sometimes camouflage email addresses to make collecting such information difficult for spammers. For example, on some sites you'll find the @ sign in an email address replaced with the word “at.”

Now we'll look at some special characters that Google doesn't ignore.
