为什么搜索引擎会忽略符号? [英] Why do search engines ignore symbols?

问题描述

在编程中通常会搜索符号，特别是在您不熟悉某种语言时. 例如，我有一个关于Python中::运算符的问题，那是不可搜索的.寻找这种或Object [](对象数组)之类的东西的人找不到他们想要的东西.

Searching for symbols is a common in programming, especially when you are new to a language. For example, I had a question about the :: operator in Python, and that is not searchable. People looking for things like this or Object [] (array of Objects), would not find what they want.

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?

Why do search engines seem to ignore symbols completely? They are just characters like any others. I can see why it would be hard to extract semantics from symbols compared to words (eg: a search engine can figure out that "find," "finds," "found" are all related, if not the same word), but is it really that hard to search for them?

我还可以看到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::)

I can also see why in everyday use you'd want symbols to be ignored, but how hard would it be to make it look for something explicitly (eg: "::" would search for ::)
