Abstract

There are various types of search techniques developed so far for searching the numbers, searching strings and others. Searching in large database containing huge collection of data is done (in most of the cases) using numerical indexes. Though there are many efficient search methods available still they are not ideal. The ideal search is the one that performs search in constant time, i.e. O(1). Till now this case is considered impossible but still we can achieve a performance very close to it using hash table. But this “The Ideal Search” can search any integer number among billions of numbers at constant O(1) time.

理想搜索
到目前为止,已经开发了各种类型的搜索技术,用于搜索数字、搜索字符串等。在包含大量数据的大型数据库中进行搜索(在大多数情况下)使用数字索引。虽然有许多有效的搜索方法,但它们并不理想。理想搜索是在常数时间内进行搜索,即O(1)。到目前为止,这种情况被认为是不可能的,但我们仍然可以使用哈希表实现非常接近的性能。但这种“理想搜索”可以在恒定的0(1)时间内搜索数十亿个数字中的任何整数。
