在这个Solr自动完成示例的示例中，我们将讨论如何为任何UI组件实现自动完成功能。我们将使用jQuery自动完成功能以及Solr索引数据来实现自动完成功能。

我们对这个例子的首选环境是solr-5.0.0，Eclipse Luna，JDK 8u25和Tomcat 8应用服务器。话虽如此，我们也测试了JDK 1.7和Tomcat 7的代码。

在您开始安装Solr的确保你已经安装了JDK和Java_Home设置为合适。

1.安装Apache Solr

首先，从以下位置下载最新版本的Apache Solr。

http://lucene.apache.org/solr/downloads.html

截至本文，稳定版本可用是5.0.0。 Apache Solr已经经历了从4.xx到5.0.0的各种更改，因此如果您有不同版本的Solr，则需要下载5.xx版本以遵循此示例。

下载Solr zip文件后，将其解压缩到文件夹中。提取的文件夹将如下所示。

Solr文件夹

该bin文件夹中包含的脚本来启动和停止服务器。该example文件夹包含几个示例文件。我们将使用其中一个来演示Solr如何对数据进行索引。该server文件夹包含logs ，所有的Solr的日志写入文件夹。在索引期间检查日志中的任何错误将是有帮助的。该solr下服务器文件夹包含不同的集合或核心。每个核/集合的配置和数据存储在相应的核/集合文件夹中。

Apache Solr附带了一个内置的Jetty服务器。但在我们启动solr实例之前，我们必须验证JAVA_HOME是否在机器上设置。

我们可以使用命令行脚本启动服务器。让我们从命令提示符转到bin目录并发出以下命令

solr start

这将在默认端口8983下启动Solr服务器。

我们现在可以在浏览器中打开以下URL，并验证我们的Solr实例正在运行。 solr管理工具的具体细节超出了示例的范围。

http://localhost:8983/solr/

Solr管理控制台

2.配置Apache Solr

在本节中，我们将向您展示如何配置solr实例的核心/集合以及如何定义字段。 Apache Solr附带一个名为Schemaless模式的选项。此选项允许用户构建有效的模式，而无需手动编辑模式文件。但是对于这个例子，我们将使用Schema配置来理解Solr的内部。

2.1创建核心

当Solr服务器在独立模式下启动时，配置称为核心，当它在SolrCloud模式下启动时，配置称为集合。在这个例子中，我们将讨论独立的服务器和核心。我们将暂停SolrCloud讨论以供日后使用。

首先，我们需要创建一个用于索引数据的Core。 Solr create命令有以下选项：

-c <名称> -芯或集合的名称来创建（必需）。
-d <confdir> -配置目录，在SolrCloud模式是有用的。
-n <CONFIGNAME> -配置名称。此默认值与核心或集合的名称相同。
-p <端口> -本地Solr的实例的端口发送创建命令;默认情况下，脚本尝试通过查找正在运行的Solr实例来检测端口。
-s <碎片> -碎片的数量成，缺省值为1分割的集合。
-rf <复制品> -集合中的每个文件的副本的数量。默认值为1。

在本例中，我们将使用-c参数作为核心名称，使用-d参数作为配置目录。对于所有其他参数，我们使用默认设置。

现在浏览solr-5.0.0\bin在命令窗口中的文件夹，并发出以下命令。

solr create -c jcg -d basic_configs

我们可以在命令窗口中看到以下输出。

 
   1<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">Creating new core'jcg' using command:</span>使用命令创建新核心'jcg'：</span>
 
   2<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">http://localhost:8983/solr/admin/cores?action=CREATE&name=jcg&instanceDir=jcg</span> http：// localhost：8983 / solr / admin / cores？action = CREATE＆name = jcg＆instanceDir = jcg</span>
 
   3 
 
   4<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">{</span> {</span>
 
   5 <span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">"responseHeader":{</span> “responseHeader”：{</span>
 
   6 <span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">"status":0,</span> “status”：0，</span>
 
   7 <span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">"QTime":663},</span> “QTime”：663}，</span>
 
   8 <span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">"core":"jcg"}</span> “core”：“jcg”}</span>

现在我们导航到以下URL，我们可以看到jcg core被填充在核心选择器中。您还可以查看核心的统计信息。

http://localhost:8983/solr

Solr jcg core

2.2修改schema.xml文件

我们需要修改schema.xml文件的文件夹下， server\solr\jcg\conf包含的字段。我们将使用随同Solr安装一起提供的示例文件“books.csv”中的一个进行索引。该文件所在的文件夹下solr-5.0.0\example\exampledocs

现在，我们定位到该文件夹server\solr目录。你会看到一个文件夹，名为jcg创建。子文件夹即conf和data分别拥有核心的配置和索引数据。

现在编辑schema.xml在文件\server\solr\jcg\conf文件夹和唯一键元素后添加以下内容。

schema.xml

 
   1<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><uniqueKey>id</uniqueKey></span> <uniqueKey> id </ uniqueKey></span>
 
   2<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><!-- Fields added for books.csv load--></span> <！ - 为books.csv加载添加的字段 - ></span>
 
   3<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="cat"type="text_general"indexed="true"stored="true"/></span> <fieldname =“cat”type =“text_general”indexed =“true”stored =“true”/></span>
 
   4<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="name"type="text_general"indexed="true"stored="true"/></span> <fieldname =“name”type =“text_general”indexed =“true”stored =“true”/></span>
 
   5<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="price"type="tdouble"indexed="true"stored="true"/></span> <fieldname =“price”type =“tdouble”indexed =“true”stored =“true”/></span>
 
   6<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="inStock"type="boolean"indexed="true"stored="true"/></span> <fieldname =“inStock”type =“boolean”indexed =“true”saved =“true”/></span>
 
   7<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="author"type="text_general"indexed="true"stored="true"/></span> <fieldname =“author”type =“text_general”indexed =“true”stored =“true”/></span>

我们已经设置的属性indexed为true。这指定了用于索引的字段，并且可以使用索引检索记录。将值设置为false将使该字段只存储，但不能查询。

另外请注意，我们叫另一个属性stored ，并将其设置为true。这指定字段存储并可以在输出中返回。将此字段设置为false将使该字段仅编入索引，并且无法在输出中检索。

我们已经为“books.csv”文件中的字段分配了类型。 CSV文件“id”中的第一个字段由schema.xml文件的uniqueKey元素自动处理，用于建立索引。

由于我们已经修改了配置，我们必须停止和启动服务器。为此，我们需要通过命令行从bin目录发出以下命令。

solr stop -all

服务器将立即停止。现在启动服务器通过命令行从bin目录发出以下命令。

solr start

3.索引数据

Apache Solr附带一个名为SimplePostTool的独立Java程序。该程序打包成JAR，并提供与文件夹下的安装example\exampledocs 。

现在，我们定位到example\exampledocs文件夹在命令提示符处键入以下命令。您将看到一堆使用该工具的选项。

java -jar post.jar -h

正如我们前面所说，我们将索引solr安装附带的“books.csv”文件中的数据。我们将导航到solr-5.0.0\example\exampledocs在命令提示符并发出以下命令。

java -Dtype=text/csv -Durl=http://localhost:8983/solr/jcg/update -jar post.jar books.csv

这里使用的SystemProperties是：

-Dtype - 数据文件的类型。
-Durl - jcg核心的URL。

文件“books.csv”现在将被索引，并且命令提示符将显示以下输出。

 
   1<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">SimplePostTool version 5.0.0</span> SimplePostTool版本5.0.0</span>
 
   2<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">Posting files to [base] urlhttp://localhost:8983/solr/jcg/update using content-</span>将文件发布到[base] url http：// localhost：8983 / solr / jcg / update using content-</span>
 
   3<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">typetext/csv...</span>键入text / csv ...</span>
 
   4<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">POSTingfile books.csv to [base]</span>将文件books.csv发布到[base]</span>
 
   5<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">1 files indexed.</span> 1个文件已索引。</span>
 
   6<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">COMMITting Solr index changes tohttp://localhost:8983/solr/jcg/update...</span>提交Solr索引更改为http：// localhost：8983 / solr / jcg / update ...</span>
 
   7<span class="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><span class="google-src-text"style="direction: ltr; text-align: left">Time spent: 0:00:00.647</span>所用时间：0：00：00.647</span>

4.设置Web项目

我们将使用jQuery自动完成小部件来消费来自Solr的数据。首先，我们将为一个简单的Web应用程序设置maven项目。

在eclipse去文件 - >新建 - >其他 - > Maven项目。

Maven - 步骤1

在向导的“选择项目名称和位置”页中，确保“创建一个简单的项目（跳过原型选择）”选项未被选中 ，点击“下一步”继续使用默认值。

Maven - 步骤2

在这里选择“maven-archetype-webapp”，然后单击下一步。

Maven - 步骤3

在向导的“输入工件ID”页面中，您可以定义项目的名称和主包。设置“组ID”变量"com.javacodegeeks.snippets.enterprise"和“工件ID”变量"solrautocomplete" 。对于包进入"com.javacodegreeks.solrautocomplete" ，然后点击“完成”退出向导并创建项目。

Maven - 步骤4

如果在index.jsp中看到任何错误，请为项目设置目标运行时。

Maven - 步骤5

现在创建一个名为search.html在WebApp文件夹。我们使用托管在云上的jQuery。我们将使用jQuery AJAX从Solr获取数据并绑定到自动完成功能的源。

search.html

由于Solr在不同的端口上运行，请求（网页）从另一个端口启动，因此我们可能会遇到跨域问题。为了克服这个问题，我们必须使用jsonp 。 minLength参数指定搜索要输入的字符数量。在这里，我们将值指定为1，这意味着当单个字符键入时，结果被绑定。

现在我们可以使用Run as - > Maven clean然后Run as - > Maven install来创建部署包。这将在目标文件夹中创建一个war文件。在war产生的文件必须放在webapps的tomcat的文件夹中。现在我们可以启动服务器了。

打开以下URL并键入“A”。这将带来的书籍有标题A的结果。

http://localhost:8080/solrautocomplete/search.html

输出1

现在在搜索框中键入“The”。这将返回有词的书。

输出2

上述索引技术的问题是我们不能基于短语获得结果。说如果我们键入“黑色”，它不会获取任何结果。此外，当我们键入'bla'没有结果绑定。为了克服这个问题，我们将使用NGramFilterFactory并重新索引数据。

5.使用NGramFilterFactory进行索引

我们将字段复制name到一个所谓的新领域name_ngram 。在将文档添加到索引时，copyField命令将一个字段复制到另一个字段。它用于以不同方式对同一字段建立索引，或者将多个字段添加到同一字段，以便更容易/更快速地搜索。

现在，修改schema.xml文件中的\server\solr\jcg\conf文件夹，并添加以下突出显示的内容。

schema.xml

 
   1<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><!--</span> <！ - </span>
 
   2<span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><copyField source="title" dest="text"/></span> <copyField source =“title”dest =“text”/></span>
 
   3<span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><copyField source="body" dest="text"/></span> <copyField source =“body”dest =“text”/></span>
 
   4<span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left">--></span> - ></span>
 
   5<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><copyFieldsource="name"dest="name_ngram"/></span> <copyFieldsource =“name”dest =“name_ngram”/></span>

在同一文件中，我们需要添加一个字段名为name_ngram并将其标记索引。对于它，我们需要添加突出显示的行。

schema.xml

 
   1<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><uniqueKey>id</uniqueKey></span> <uniqueKey> id </ uniqueKey></span>

   4<spanclass="notranslate"onmouseover="_tipon(this)"onmouseout="_tipoff()"><spanclass="google-src-text"style="direction: ltr; text-align: left"><fieldname="name"type="text_general"indexed="true"stored="true"/></span> <fieldname =“name”type =“text_general”indexed =“true”stored =“true”/></span>

就拿我们已经改变了新的领域作为类型的说明text_ngram 。我们将定义类型text_ngram其后。

现在我们添加了定义字段text_ngram中schema.xml文件。我们已将最小ngram大小设置为2，最大ngram大小设置为10。

schema.xml

我们结合的特点NGramTokenizerFactory和EdgeNGramTokenizerFactory达到最佳的索引。由于我们已经修改了配置，我们必须停止和启动服务器。要做到这一点，我们需要从发出以下命令bin通过命令行目录。

solr stop -all

服务器将立即停止。现在启动服务器从bin目录通过命令行发出以下命令。

solr start

我们将重新索引存在于数据books.csv文件。我们将导航到solr-5.0.0\example\exampledocs在命令提示符并发出以下命令。

java -Dtype=text/csv -Durl=http://localhost:8983/solr/jcg/update -jar post.jar books.csv

该文件books.csv现在将重新索引和命令提示将显示以下的输出。

6.修改search.html

现在，我们将修改search.html包含另一个搜索框测试NGRAM索引。我们将创建一个ID搜索框ngrambox和写入新的搜索框，另一个JavaScript函数。
