If you're not sure you're ready to dive into this depth, take a look at my not-so-nitty-gritty overview.
如果你确定你不准备深究，看一看我的另一篇文章——Lucene概观。
2
I've introduced you to the main index files in Lucene, hopefully allowing you to understand the physical storage structure of Lucene.
到目前为止我们介绍了Lucene中的主要的索引文件结构，希望能对你理解Lucene的物理的存储结构有所帮助。
3
It should be noted that while Lucene is a search engine, it has no crawling capability.
需要注意的是，虽然Lucene是一个搜索引擎，但它没有爬行能力。
4
Alternately, a plain text search string, perhaps entered by an end-user, can be parsed and executed.
其次，Lucene可以解析并执行（可能由最终用户输入的）普通文本搜索字符串。
5
Lucene's index database is composed of a number of separate "segments" each stored in an individual file.
Lucene的索引数据库是由几个独立的“段（segment）”组成，每个都存储在一个独立的文件中。
6
You'll notice the same theme if you hang out on the lucene-user list and listen to Doug Cutting answering questions.
如果你在Lucene用户列表上闲逛或者听DougCutting回答问题，你会看到同样的主题。
7
(You can safely skip this section, as it's just me meandering through the Lucene source code; not a whole lot of practical value here yet).
你可以放心地跳过这一节，这只是我在Lucene源码中漫步；这并没有很多实际价值。
8
This will produce a subdirectory called index which will contain an index of all of the Lucene source code.
这个命令会创建一个名为index的子目录，这个目录包含了所有Lucene源码的索引。
9
First, as a way of introduction, Solr (really Lucene) uses a Java class called Searcher to process Query instances.
首先，作为一种介绍的方式，Solr（实际上是Lucene）使用称为Searcher的Java类来处理Query实例。
10
Optimization results in the merging of many of the Lucene index files into a single file.
优化会导致多个Lucene索引文件合并成一个单一文件。
11
This directory contains the search index files produced by the Lucene search engine as shown in Figure 10.
此目录包含Lucene搜索引擎产生的搜索索引文件，如图10中所示。
12
With that upgrade, the Lucene component gained three powerful advanced-search options.
通过这一升级，Lucene组件获得了三种强大的高级搜索选项。
13
To start using it, one needs to know only a few Lucene classes and methods.
你仅需要知道一些Lucene类和方法就可以踏上使用的道路了。
14
You can have more control over the analysis process by creating custom analyzers using basic building blocks provided by Lucene.
您可以使用Lucene提供的基本构建块创建定制分析程序，以自己的方式控制分析过程。
15
This section is intended for Java developers wishing to understand how to use Lucene in their applications.
本章适用于那些想知道如何在他们的程序中使用Lucene的Java开发者们。
16
This function is explained next and is responsible for adding any matching files into the Lucene search index.
此函数将在后面进行说明，负责将任何匹配的文件添加到Lucene搜索引擎。
17
The Java JIT is switched on in these timings, and in an application like Lucene, it makes a considerable difference in execution times.
所有这些计时都打开了JavaJIT，这在Lucene之类的应用程序中的执行时间方面会产生巨大的差异。
18
Lucene is great, but in its current form it has several shortcomings for real-time search.
Lucene是伟大的，但是它现在的方法在实时搜索上还存在几个缺陷。
19
Underneath the hood, Lucene must enumerate the terms in the documents to identify documents that fall within the range.
在处理过程中，Lucene必须枚举文档中的词汇以识别在范围之内的所有文档。
20
Although location information can be represented in several ways, I'll focus on the ones pertinent to Lucene.
尽管可以通过几种方式来表示位置信息，但我仅关注与Lucene相关的方式。
21
The slave servers then use rsync to copy only those files in the Lucene index that have been changed.
之后，从服务器使用rsync来只复制Lucene索引中的那些已被更改的文件。
22
Although Lucene is a search index, and not a database, if your fields are reasonably small, you can ask Lucene to store them in the index.
虽然Lucene是一个搜索索引而非一个数据库，但是如果这个字段相当小，你可以让Lucene把它们存在索引里面。
23
Get Luke: A very handy tool for examining the contents of a Lucene index.
获取Luke：一种检查Lucene索引的便捷工具。
24
Lucene indexes text, and part of the first step is cleaning up the text.
Lucene对一个文本建索引，第一步的部分工作是整理这个文本。
25
Searching: This subsystem searches on the Lucene index and returns the search results to the Request Manager subsystem.
搜索子系统：这个子系统负责在索引文件上进行搜索并把搜索结构传递给请求管理器。
26
I'll start with a brief review of some key Lucene concepts, leaving the deeper details to the reader to research.
我首先简单介绍Lucene的一些关键概念，深入的细节留给读者自己探索。
27
Lucene is not a crawling search engine, nor does it automatically index content.
Lucene并不是一个爬行搜索引擎，也不会自动地索引内容。
28
Better performance on projected properties (no noticeable overhead compared to raw Lucene calls).
对受保护的属性的更好的性能（相比于原生的Lucene调用并没有明显的代价）。
29
It also briefly describes the fundamental process and related API of using Lucene to implement the index and search function.
简单说明了采用Lucene进行索引和搜索的基本过程和相关的API。
30
They have been planning on eventually migrating to competing search engine called Lucene. Net.
他们已经规划出迁移到竞争的搜索引擎Lucene.Net上。
