这段英文怎么理解？有知道的朋友告诉下，谢谢。



Condition: Offset modulo x = y: The search algorithm accepts search string occurrences only at offsets that meet the given requirements. E. g. if you search for data that typically occurs at the 10th byte of a hard disk sector, you may specify x=512, y=10. If you are looking for DWORD-aligned data, you may use x=4, y=0 to narrow down the number of hits.


翻译：

条件:抵消模x = y:搜索算法只接受搜索字符串出现的偏移量,满足给定的需求。e . g .如果您搜索数据,通常发生在10字节的硬盘,你可以指定x = 512,y = 10。如果你正在寻找DWORD-aligned数据,您可以使用x = 4,y = 0的数量缩小。
