推荐答案

如上所述，未锚定在字符串开头的正则表达式搜索可能会非常昂贵，因为它们需要进行全表扫描.根据您的用例，您可能会考虑使用文本索引.它为不区分大小写的非锚定搜索(包括后缀词干)提供支持.

As was mentioned above, regex searches that are not anchored at the beginning of the string can be very expensive because they require a full table scan. Depending on your use case you might consider using a text index instead. It provides support for case-insensitive non-anchored searches including suffix stemming.
