索引文件

For example, when visiting a file, the FAT file system as a result of the file allocation table lists only the name of each file and the initial cluster, and did not say whether the document exists, and through their records in the folder to determine, and import folder and file allocation table is included in the index.

例如当访问一个文件时，由于FAT文件系统的文件分配表只列出了每个文件的名称及起始簇，并没有说明这个文件是否存在，而需要通过其所在文件夹的记录来判断，而文件夹的入口又包含在文件分配表的索引中。

Keyword index is a data structure that allows us to search in constant time for documents containing specified keywords. Unfortunately, standard index constructions are not designed for encrypted documents, because they may leak some information about the document. In this thesis, we propose two index structures called PRP-Index and P-Index which are designed for encrypted documents.

中文摘要关键字索引搜寻为一种加速文件关键字搜寻的一种架构，但是随著文件的安全性越来越受到重视，文件开始以加密的型态储存於资料库，但是目前的索引架构并没有针对加密文件作考量，也因此索引有可能会透露出文件的相关资讯，造成安全上的问题。

The Google Search Appliance crawls your content and creates a master index of documents that's ready for instant retrieval using Google's search technology, whenever a customer or employee types in a search query.

如何搜索谷歌家电爬你的作品内涵，创造了总索引文件的准备速食谷歌检索使用的搜寻技术，每当有员工或客户类型搜索质疑。

The retrieval of a data record in an indexed file by the primary key within the data record

在索引文件中，通过数据记录中的主要关键字或可选关键字进行数据记录的检索的一种方法。

Fig. 3 shows that in order to navigate to a related record, the secondary key is used to find the primary key in an index file, which contains a sorted list of keys and physical addresses for each table record.

无花果。 3表明，以切换到了相关的记录，中学主要是用来寻找的首要关键，在一个索引文件，其中包含一个排序名单钥匙和物理地址，每个表记录。

Maintain supplier indexed file of purchasing related correspondence.

When POI is loaded for the first time, the program will pause very long time at the startup screen to generate the index file, just wait only, next time the startup will be normal again.

当POI第一次被装载，节目将停留非常很长时间在启动屏幕引起索引文件，仅等待，起动再将是正常的下次

Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.

坐标序列法是由多边形边界的x，y坐标对集合及说明信息组成，是最简单的一种多边形矢量编码法，文件结构简单，但多边形边界被存储两次产生数据冗余，而且缺少邻域信息；树状索引编码法是将所有边界点进行数字化，顺序存储坐标对，由点索引与边界线号相联系，以线索引与各多边形相联系，形成树状索引结构，消除了相邻多边形边界数据冗余问题；拓扑结构编码法是通过建立一个完整的拓扑关系结构，彻底解决邻域和岛状信息处理问题的方法，但增加了算法的复杂性和数据库的大小。

This is because Windows 7 searches inside contents of only those files which are indexed.

这是因为Windows 7的搜索里面只有那些被索引文件的内容。

Steg B(superscript +)-Tree, which uses steganographic technologies to overcome above mentioned weakness is presented by hiding the existence of data so that an adversary could get no information about whether the protected data ever exists without correct object name and access key.

介绍一种新的着重于隐藏数据的存在性的加密手段－隐文加密（Steganography，隐写术）来对重要文件的存储进行加密，该方法采用隐文B树Steg B(上标+ Tree建立UNIX系统的文件索引，并通过隐藏表将隐文B树索引隐蔽起来，使攻击者无法知道重要信息的存在，从而使要保护的信息更安全。
