Solr Lucene

solr 4.1 install guide

1.从Solr的官方网站下载Solr 4.1的安装包.

2.解压solr-4.1.0.zip 到安装目录。

3.将 solr-4.1.0目录下的example复制成目标索引项目的名称 cloudatlas.

4.进行 solr-4.1.0\cloudatlas\solr目录，复制 collection1 为索引文档的名称。
collection1 –> photos, users.

5.在 solr-4.1.0\cloudatlas\solr\solr.xml文件中，配置两个core 实例。

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
  <cores defaultCoreName="photos" adminPath="/admin/cores" zkClientTimeout="${zkClientTimeout:15000}" hostPort="8983" hostContext="solr">
    <core name="photos" loadOnStartup="true" instanceDir="photos\" transient="false" />
    <core name="users"  loadOnStartup="true" instanceDir="users\" transient="false" />
  </cores>
</solr>

6.配置IK中文分词。

在 [googlecode](https://code.google.com/p/ik-analyzer/) 下载IK分词器的 jar 包。    在 solr-4.1.0\cloudatlas\solr 下创建 lib 目录，并将下载的IK分词器jar放到该目录中。

在 solr-4.1.0\cloudatlas\solr\photos\conf\solrconfig.xml 配置lib 目录  

<lib dir="../lib" />

在 solr-4.1.0\cloudatlas\solr\photos\conf\schema.xml 配置中文分词的field_type.

 <fieldType name="text_cn" class="solr.TextField" positionIncrementGap="100">
  <analyzer type="index">
    <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" useSmart ="false"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" useSmart ="false"/>
  </analyzer>
</fieldType>


采用中文分词的field配置：

    <field name="photo_desc" type="text_cn" indexed="true" stored="true"/>

7.在solr.xml 中注释 elevator 的配置（因为我们的schema 字段配置与 elevate中的字段配置有冲突）

<!-- Query Elevation Component

     http://wiki.apache.org/solr/QueryElevationComponent

     a search component that enables you to configure the top
     results for a given query regardless of the normal lucene
     scoring.
  -->
<searchComponent name="elevator" class="solr.QueryElevationComponent" >
  <!-- pick a fieldType to analyze queries -->
  <str name="queryFieldType">string</str>
  <str name="config-file">elevate.xml</str>
</searchComponent>

<!-- A request handler for demonstrating the elevator component -->
<requestHandler name="/elevate" class="solr.SearchHandler" startup="lazy">
  <lst name="defaults">
    <str name="echoParams">explicit</str>
    <str name="df">text</str>
  </lst>
  <arr name="last-components">
    <str>elevator</str>
  </arr>
</requestHandler>

8.配置索引的文档schema.

photos的schema.xml 配置

<?xml version="1.0" encoding="UTF-8" ?>    
<schema name="photos" version="1.5">

 <fields>        
   <field name="id" type="long" indexed="true" stored="true" required="true" multiValued="false" /> 
   <field name="user_id" type="long" indexed="true" stored="true" omitNorms="true" />   
   <field name="folder_id" type="long" indexed="true" stored="true" omitNorms="true" />   
   <field name="folder_name" type="text_cn" indexed="true" stored="true"/>
   <field name="folder_desc" type="text_cn" indexed="true" stored="true"/>
   <field name="photo_desc" type="text_cn" indexed="true" stored="true"/>
   <field name="farm" type="string" indexed="false" stored="true" omitNorms="true"/>
   <field name="bucket" type="string" indexed="false" stored="true" omitNorms="true"/>
   <field name="storage_keys" type="string" indexed="false" stored="true" omitNorms="true"/>
   <!-- catchall field, containing all other searchable text fields (implemented
        via copyField further on in this schema  -->
   <field name="text" type="text_cn" indexed="true" stored="false" multiValued="true"/>
   <field name="_version_" type="long" indexed="true" stored="true" multiValued="false" />   
 </fields>


 <!-- Field to use to determine and enforce document uniqueness. 
      Unless this field is marked with required="false", it will be a required field
   -->
 <uniqueKey>id</uniqueKey>

   <copyField source="folder_name" dest="text"/>
   <copyField source="folder_desc" dest="text"/>
   <copyField source="photo_desc" dest="text"/>  

  <types>

    <!-- The StrField type is not analyzed, but indexed/stored verbatim. -->
    <fieldType name="string" class="solr.StrField" sortMissingLast="true" />

    <!-- boolean type: "true" or "false" -->
    <fieldType name="boolean" class="solr.BoolField" sortMissingLast="true"/>

    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="float" class="solr.TrieFloatField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" positionIncrementGap="0"/>

    <fieldType name="text_cn" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" useSmart ="false"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" useSmart ="false"/>
      </analyzer>
    </fieldType>
 </types>

    <!-- field for the QueryParser to use when an explicit fieldname is absent -->
    <defaultSearchField>text</defaultSearchField>

    <!-- SolrQueryParser configuration: defaultOperator="AND|OR" -->
    <solrQueryParser defaultOperator="OR"/>

</schema>

users的schema 配置

<?xml version="1.0" encoding="UTF-8" ?>

<schema name="users" version="1.5">

 <fields>        
   <field name="id" type="long" indexed="true" stored="true" required="true" multiValued="false" /> 
   <field name="nickname" type="text_cn" indexed="true" stored="true"/>
   <field name="text" type="string" indexed="true" stored="false" multiValued="true"/>
   <field name="_version_" type="long" indexed="true" stored="true" multiValued="false" />
 </fields>


 <!-- Field to use to determine and enforce document uniqueness. 
      Unless this field is marked with required="false", it will be a required field
   -->
 <uniqueKey>id</uniqueKey>

<!--
   <copyField source="folder_name" dest="text"/>
   <copyField source="folder_desc" dest="text"/>
   <copyField source="photo_desc" dest="text"/>  
 -->

  <types>
    <!-- The StrField type is not analyzed, but indexed/stored verbatim. -->
    <fieldType name="string" class="solr.StrField" sortMissingLast="true" />

    <!-- boolean type: "true" or "false" -->
    <fieldType name="boolean" class="solr.BoolField" sortMissingLast="true"/>

    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>

10.启动solr 服务 

java -jar start.jar
