Solr空间搜索之周边酒店搜索

现在移动开发中越来越多的App都有周边搜索，有找附近的人的，附近的酒店，附近的餐馆的。接下来我们就来讲一下强大的Solr来帮我们构建周边搜索之酒店搜索。

1 下载 Solr 3.6.2

   下载地址:http://www.apache.org/dyn/closer.cgi/lucene/solr/3.6.2 

    提取apache-solr-3.6.2.zip里的apache-solr-3.6.2.war到F:\, 后面会讲解如何部署这个war包

2 建立solr的索引库配置

   2.1 在D:\建立目录hotel_solr

   2.2 在D:\hotel_solr下新建solr.xml,内容如下:

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="false">
  <cores adminPath="/admin/cores">
    <core name="core0" instanceDir="core0" />
    <!--<core name="core1" instanceDir="core1" />-->
  </cores>
</solr>

   2.3 在D:\hotel_solr新建core0\conf目录

   2.4 在D:\hotel_solr\core0\conf目录下，新建schema.xml文件,内容如下:

<?xml version="1.0" ?>
<schema name="example core zero" version="1.1">
  <types>
   <fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="boolean" class="solr.BoolField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="integer" class="solr.IntField" omitNorms="true"/>
         <fieldType name="int" class="solr.TrieIntField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="float" class="solr.TrieFloatField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="long" class="solr.TrieLongField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="tint" class="solr.TrieIntField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="tfloat" class="solr.TrieFloatField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="tlong" class="solr.TrieLongField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="tdouble" class="solr.TrieDoubleField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
         <fieldType name="sint" class="solr.SortableIntField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="slong" class="solr.SortableLongField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="sfloat" class="solr.SortableFloatField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="sdouble" class="solr.SortableDoubleField" sortMissingLast="true" omitNorms="true"/>
         <fieldType name="date" class="solr.TrieDateField" omitNorms="true" precisionStep="0" positionIncrementGap="0"/>
         <fieldType name="tdate" class="solr.TrieDateField" omitNorms="true" precisionStep="6" positionIncrementGap="0"/>
         <fieldtype name="ignored" stored="false" indexed="false" class="solr.StrField"/>
         <fieldtype name="location" class="solr.LatLonType" subFieldSuffix="_d"/>
         <fieldType name="text" class="solr.TextField" positionIncrementGap="100">
               <analyzer type="index">
                 <tokenizer class="solr.StandardTokenizerFactory"/>
                 <filter class="solr.LowerCaseFilterFactory"/>
               </analyzer>
               <analyzer type="query">
                 <tokenizer class="solr.StandardTokenizerFactory"/>
                 <filter class="solr.LowerCaseFilterFactory"/>
               </analyzer>
         </fieldType>
  </types>
 <fields>
  <field name="hotel_id" type="integer" indexed="true" stored="true" required="true"/>
  <field name="crawl_hotel_id"    type="string"   indexed="true"  stored="true"  multiValued="false" required="true"/> 
  <field name="name"    type="text"   indexed="true"  stored="true"  multiValued="false" required="true"/> 
  <field name="address"    type="text"   indexed="true"  stored="true"  multiValued="false" required="true"/> 
  <field name="search_kw" type="text" indexed="true" multiValued="true" stored="false" /> 
  <field name="latlng" type="location" indexed="true" />
  <dynamicField name="*_d" type="double" indexed="true" stored="true"/>
 </fields>
 <copyField source="name" dest="search_kw" />
 <copyField source="address" dest="search_kw" />
 <uniqueKey>hotel_id</uniqueKey>
 <defaultSearchField>search_kw</defaultSearchField>
 <solrQueryParser defaultOperator="AND"/>
</schema>

    2.5 在D:\hotel_solr\core0\conf目录下，新建solrconfig.xml文件,内容如下:

<?xml version="1.0" encoding="UTF-8" ?>
<config>
  <luceneMatchVersion>LUCENE_36</luceneMatchVersion>
  <directoryFactory name="DirectoryFactory" class="${solr.directoryFactory:solr.StandardDirectoryFactory}"/>
  <updateHandler class="solr.DirectUpdateHandler2" />
  <requestDispatcher handleSelect="true" >
    <requestParsers enableRemoteStreaming="false" multipartUploadLimitInKB="2048" />
  </requestDispatcher>
  <requestHandler name="standard" class="solr.StandardRequestHandler" default="true" />
  <requestHandler name="/update" class="solr.XmlUpdateRequestHandler" />
  <requestHandler name="/admin/" class="org.apache.solr.handler.admin.AdminHandlers" />
  <admin>
    <defaultQuery>*:*</defaultQuery>
  </admin>
</config>

    到这里为止Solr的索引配置完成.

3 配置tomcat

   3.1 让tomcat支持HTTP GET UTF-8编码的支持, 打开D:\apache-tomcat-7.0.16\conf\server.xml，修成如下地方:

<Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" URIEncoding="UTF-8"/>

   3.2 配置solr的war包

         在D:\apache-tomcat-7.0.16\conf\Catalina\localhost新建solr.xml,内容如下:

<Context docBase="F:/apache-solr-3.6.2.war" debug="0" crossContext="true" >  
  <Environment name="solr/home" type="java.lang.String" value="D:/hotel_solr" override="true" />  
</Context>

   3.3 启动tomcat, 在浏览器中输入:http://localhost:8080/solr/   如果出现Admin core0 表示正常。
