#solr server版本:  7.7.1 / 7.7.2

#java jdk版本1.8

网上教程1.5.5.RELEASE会版本冲突,其他版本未知
org.springframework.data : 2.1.1.RELEASE

##简单sol安装(内置)
### http://archive.apache.org/dist/lucene/solr/7.7.1/solr-7.7.1.tgz
将 solr-7.7.1\server\lib\ext  所有jar复制到  webapps\solr\WEB-INF\lib
将 solr-7.7.1\server\lib    metrics开头的所有jar包，以及gmetric4j-1.0.7.jar复制到 webapps\solr\WEB-INF\lib

在 solr-7.7.1\server 下新建 logs 目录

在 solr-7.7.1\server\solr 新建core,例如 lhc_core

将 solr-7.7.1\server\solr\configsets\_default\conf 下所有文件复制到  lhc_core 目录

启动,新建该core


##ik分词器配置
### https://search.maven.org/search?q=com.github.magese

将  ik-analyzer-solr7-7.x.jar  复制到 solr-7.7.1\server\solr-webapp\webapp\WEB-INF\lib
将减压后的resources文件夹下的IKAnalyzer.cfg.xml , ext.dic和stopword.dic 三个文件 复制到solr-7.7.1\server\solr-webapp\webapp\WEB-INF\classes



managed-schema添加

```
<!-- ik分词器 -->
<fieldType name="text_ik" class="solr.TextField">
    <analyzer type="index">
      <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" conf="ik.conf" useSmart="false"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
      <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" conf="ik.conf" useSmart="true"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
</fieldType>

```



##中文拼音搜索配置
### http://www.java2s.com/Code/Jar/p/Downloadpinyin4j250jar.htm

pinyin4j-2.5.0.jar  pinyinAnalyzer4.3.1.jar 复制到 solr-webapp\webapp\WEB-INF\lib
managed-schema添加
```
<!-- 中文拼音 -->
<fieldType name="text_pinyin" class="solr.TextField" positionIncrementGap="0">
    <analyzer type="index">
        <tokenizer class="org.apache.lucene.analysis.ik.IKTokenizerFactory"/>
        <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" />
        <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="1" maxGram="20" />
    </analyzer>
    <analyzer type="query">
        <tokenizer class="org.apache.lucene.analysis.ik.IKTokenizerFactory"/>
        <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" />
        <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="1" maxGram="20" />
    </analyzer>
</fieldType>
```

##dataimport配置
将 solr-7.7.1\dist 目录下 solr-dataimporthandler-7.7.1.jar solr-dataimporthandler-7.7.1.jar 复制到 solr-webapp\webapp\WEB-INF\lib
复制  mysql-connector  jar包到  solr-webapp\webapp\WEB-INF\lib
修改 solrconfig.xml

```
<requestHandler name="/dataimport" class="solr.DataImportHandler">
    <lst name="defaults">
      <str name="config">data-config.xml</str>
    </lst>
</requestHandler>
```

有的可能需要修改 solrconfig里 
```
<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
```

##配置suggest联想搜索


managed-schema添加

```
<!-- text_suggest 类型定义-->
<fieldType name="text_suggest" class="solr.TextField">  
    <analyzer type="index">  
        <tokenizer class="solr.KeywordTokenizerFactory"/>  
        <filter class="solr.LowerCaseFilterFactory"/>  
    </analyzer>  
    <analyzer type="query">  
        <tokenizer class="solr.KeywordTokenizerFactory"/>  
        <filter class="solr.LowerCaseFilterFactory"/>  
    </analyzer>  
</fieldType>
```


solrconfig.xml添加
```
<searchComponent name="suggest" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">string</str>
     <lst name="spellchecker">
          <str name="name">suggest</str>
          <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
		  <str name="dictionaryImpl">FileDictionaryFactory</str>
			<!-- <str name="sourceLocation">D:\solr-7.7.1\server\solr\lhc_core\conf\suggest\dict.txt</str> -->
          <!-- <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str> -->
		  <str name="suggestAnalyzerFieldType">text_ik</str>
		  <float name="threshold">0.0001</float>
          <str name="field">search</str>
		  <str name="comparatorClass">freq</str>
        <str name="buildOnOptimize">true</str>
		<str name="buildOnCommit">true</str>  
     </lst>
</searchComponent>
<requestHandler name="/suggest" class="org.apache.solr.handler.component.SearchHandler">
     <lst name="defaults">
          <str name="spellcheck">true</str>
          <str name="spellcheck.dictionary">suggest</str>
          <str name="spellcheck.count">10</str>
		  <str name="spellcheck.onlyMorePopular">true</str>
		<str name="spellcheck.extendedResults">false</str>		
		<str name="spellcheck.collate">true</str>
     </lst>
     <arr name="components">
          <str>suggest</str>
     </arr>
</requestHandler>
```
即使将联想字段设置为type="text_ik",有时候也并不一定能关联搜索到
如果添加 dictionaryImpl  sourceLocation 配置则联想搜索该文件 需要手动维护
需要权衡自动根据字段联想还是手动配置
注意联想搜索需要两个字以上且最左匹配原则

测试suggest:
http://127.0.0.1:8983/solr/lhc_core/suggest?qt=suggest&suggest=true&suggest.build=true&suggest.dictionary=mySuggester&wt=json&suggest.q=华为 

使suggeest/dict.txt即时生效:
http://127.0.0.1:8983/solr/lhc_core/suggest?spellcheck.build=true

dict.txt格式为  联想字符[Tab]权重值,例如: 华为    2.3
##field配置
```
<field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
<field name="name1" type="text_ik" indexed="true" stored="true"/>
<field name="brandName" type="text_ik" indexed="true" stored="true"/>
<field name="productCateId" type="pint" indexed="false" stored="true"/>
<field name="cId" type="string" indexed="false" stored="true"/>
<field name="keyword" type="text_ik" indexed="true" stored="true"/>
<field name="price" type="false" indexed="true" stored="true"/>
<field name="search" type="text_ik" multiValued="true" indexed="true" stored="true"/>

<copyField source="name1" dest="search" maxChars="30000"/>
<copyField source="brandName" dest="search" maxChars="30000"/>
<copyField source="keyword" dest="search" maxChars="30000"/>
```

##如果启动solr提示 _root_ _version_ 等错误则添加

```
<field name="_root_" type="string" docValues="false" indexed="true" stored="false"/>
<field name="_text_" type="text_general" multiValued="true" indexed="true" stored="false"/>
<field name="_version_" type="plong" indexed="false" stored="false"/>
```
