从区分大小写映射到不区分大小写现在看来是很微不足道的，但实际上很难有效地进行这一映射。

Now it would seem fairly trivial to map from case-sensitive to case-insensitive, but in fact it's hard to do it efficiently.

例如，将反向文本索引的索引扩展参数化，以支持大小写敏感和大小写不敏感的索引。

For example, the index extension for the inverted text index can be parameterized to also support case-sensitive and case-insensitive indexes.

提示：相同的脚本可以同时为区分大小写的和不区分大小写的查询创建索引。

Tip: The same script creates indexes for both case-insensitive and case-sensitive queries.

That's pretty good 'cause now, I can pretty much cover my American keyboard pretty effectively both upper case, lower case, and a whole bunch of punctuation. For other languages as in aside, there are other encoding schemes when there are more characters.

那是相当不错的，它可以包含整个美式键盘中的字符,包括大小写字母和一连串标点,对于其他语言，当涉及更多字符时就会有其他的编码体系。

And if you've typed in l when you should've 1 typed a 1, or a 1 when you should've typed an l, you're likely to miss it. If you've made a mistake with upper and lower case. Things like that. So just be very careful looking at that.

如果你本来想打，1，的时候,却输成了，l，或者打，l，的时候输成了，你很可能注意不到这个错误,如果你把大小写弄混了也是一样,要注意这个错误。
