Based on the feature of search engine index database, a data storing model on the content and structure of documents is proposed.

探讨了搜索引擎信息标引方法和数据存储策略，并结合搜索引擎索引数据库的特点，提出了一个基于文档内容和结构的数据存储模型，以及相应的索引结构。

In this paper, an indexing scheme, inspired by the Dewey decimal notation, is proposed for simplifying the implementation of the search algorithm.

本篇文章首先介绍一种索引架构，可以简化上述搜索演算法的施行。这种索引架构，主要是起因於杜威的十进位符号观念。

If we are reading a slice of columns, we use the row-level column index to find where to start reading, and deserialize block-at-a-time (where "block" is the group of columns covered by a single index entry) so we can handle the "reversed" case without reading vast amounts into memory

如果读取的是列集合，那就要用行级列索引查找从读取的起始位置并且反序列化每个块（"块"就是单个索引所覆盖到的一组列），这样我们不需要大量占用内存就可以处理"逆向"情况。

For example, an index of n local variables, if it is a double-precision Fudianshuo, it actually occupied index n and n+1 represent storage space.

例如，一个具有索引n的局部变量，如果是一个双精度浮点数，那么它实际占据了索引n和n+1所代表的存储空间。

Multidimensional data index is a way to index the eigenvector in the multidimension space.

多维索引方法就是对多维空间中的特征向量进行索引的方法。

If there is more than one entry for a single word or phrase, then you can scroll through each of the entries.

如果一个单词或短语有多个索引，那麼可以在每个索引间滚动。

In the earlier article, I have suggested to include all columns but in reality in any non clustered index there is no need to include columns included in the clustered index.

在以前的文章中，我曾向包括所有列，但在聚集索引，没有必要在聚集索引中的任何列在非现实。

As discussed in the example, any non clustered index does not need to include columns which are included in the clustered index.

随着讨论的例子，任何非聚集索引不需要内容涉及聚集索引中的列。

Bitmap indexes can include rows that have NULL values, unlike most other types of indexes.

与其他大多数索引不同，位图索引可以包含键值为 NULL 的行。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
