索引生成器被称为索引器。
Sphinx有三个组件：索引生成器、搜索引擎和命令行search实用程序
Sphinx has three components: an index generator, a search engine, and a command-line search utility
用于在INSERT和UPDATE操作中构造索引键的键生成器函数。
Key generator function to construct index key during INSERT and UPDATE operations.
清单1.hash索引键生成器的实现。
生成器的输出是一个Web应用程序的WAR文件夹，其中包含与每个带注解的bean对应的窗口，以及用来选择窗口的索引。
The output of the generator is a WAR folder with a working Web application containing a window for each of the annotated beans found, as well as an index to choose among them.
对于索引扩展有两个需求：键生成器是确定性的，并且不使用SQL。
Two requirements from the index extensions are that the key generator is a deterministic and does not use SQL. Both are fulfilled, so the SQL statement in Listing 2 can be used to create the UDF
用于定义在查询执行期间空间索引的搜索范围的范围生成器函数。
Range producer function to define the search ranges for the spatial index during query execution.
我也修改了一下Google XML网站地图生成器，加入了给搜索引擎提交Sitemap的时间戳。
I also modified the sitemap generator to insert a timestamp every time the sitemap was submitted to the search engines.
对那些不知道GoogleXML网站地图生成器的人解释一下，这个插件当你每次在WordProess里编辑或创建文章时，都会生成一个新的Sitemap，并把Sitemap提交给主要的搜索引擎。
For those of you who don't know what the Google XML Sitemaps Generator is, every time you edit or create a post on WordPress it creates a new sitemap and submits it to the major search engines.
与hash索引一样，这里需要定义一个键生成器udf、一个范围生成器udf、一个索引扩展以及一个利用索引扩展的UDF。
As before with the hash index, you need to define a key generator UDF, a range producer UDF, the index extension, and finally a UDF that exploits the index extension if possible.
