1.环境
名称 | 地址 |
solr-integration-strategies-gh-pages.zip | |
solr-4.7.1 | |
apache-tomcat-6.0.39 | |
carrot2-webapp-3.9.2.war |
2.启动Solr
F:\solr\solr-4.7.1\example>java -Dsolr.solr.home=../../carrot2-3.8.0-4.7.1/solr-home -jar start.jar |
访问http://localhost:8983/solr/#/
3.导入数据
使用solr-docs中post.jar向solr中导入数据
F:\solr\solr-integration-strategies-gh-pages\solr-docs>java -jar post.jar 20newsgroups |
4.聚类集成到Solr中
carrot2提供的solrconfig.xml中的对搜索结果进行了配置
<lib dir="../../../solr-4.7.1/contrib/clustering/lib/" regex=".*\.jar" /> <lib dir="../../../solr-4.7.1/dist/" regex=".*solr-clustering-.*\.jar" /> |
<!-- Declare a clustering search component, configure a single engine (Lingo algorithm) --> <searchComponent name="clustering" enable="true" class="solr.clustering.ClusteringComponent" > <lst name="engine"> <str name="name">default</str> <str name="carrot.algorithm">org.carrot2.clustering.lingo.LingoClusteringAlgorithm</str> <str name="LingoClusteringAlgorithm.desiredClusterCountBase">20</str> <str name="carrot.lexicalResourcesDir">clustering/carrot2</str> <str name="MultilingualClustering.defaultLanguage">ENGLISH</str> </lst> </searchComponent> |
配置
config1_1(search handler):
<requestHandler name="/config1_1" class="solr.SearchHandler"> <lst name="defaults"> <str name="defType">edismax</str> <str name="qf">title^1.5 content^1.0</str> <str name="rows">100</str> <str name="fl">*,score</str>
<!-- Enable clustering. --> <bool name="clustering">true</bool> <!-- enable clustering --> <bool name="clustering.results">true</bool> <!-- cluster search results, not the collection --> <str name="clustering.engine">default</str> <!-- use the default engine -->
<!-- Solr-to-Carrot2 field mapping. --> <str name="carrot.url">name</str> <!-- unique ID field, doesn't have to be an URL --> <str name="carrot.title">title</str> <!-- document title field. --> <str name="carrot.snippet">content</str> <!-- document "contents" field --> </lst>
<!-- Attach clustering as the last processing component. --> <arr name="last-components"> <str>clustering</str> </arr> </requestHandler> |
config1_2 (search handler returning a subset of fields)
<requestHandler name="/config1_2" class="solr.SearchHandler"> <lst name="defaults"> <str name="defType">edismax</str> <str name="qf">title^1.5 content^1.0</str> <str name="rows">100</str>
<!--只显示name,title,content太大,不显示--> <str name="fl">name,title,score</str>
<bool name="clustering">true</bool> <bool name="clustering.results">true</bool> <str name="clustering.engine">default</str>
<str name="carrot.url">name</str> <str name="carrot.title">title</str> <str name="carrot.snippet">content</str> </lst>
<arr name="last-components"> <str>clustering</str> </arr> </requestHandler> |
config1_3(search handler returning contextual snippets)
<requestHandler name="/config1_3" class="solr.SearchHandler"> <lst name="defaults"> <str name="defType">edismax</str> <str name="qf">title^1.5 content^1.0</str> <str name="rows">100</str>
<str name="fl">name,title,score</str>
<!—对内容字段高亮 --> <bool name="hl">true</bool> <str name="hl.fl">content</str> <!-- Disable highlight wrapping. --> <str name="hl.simple.pre"><!-- --></str> <str name="hl.simple.post"><!-- --></str> <str name="f.content.hl.snippets">3</str> <!-- max 3 snippets of 200 chars. --> <str name="f.content.hl.fragsize">200</str>
<bool name="clustering">true</bool> <bool name="clustering.results">true</bool> <str name="clustering.engine">default</str>
<str name="carrot.url">name</str> <str name="carrot.title">title</str> <str name="carrot.snippet">content</str> </lst>
<arr name="last-components"> <str>clustering</str> </arr> </requestHandler> |
config2_1(search handler clustering query-in-context snippets)
<requestHandler name="/config2_1" class="solr.SearchHandler"> <lst name="defaults"> <str name="defType">edismax</str> <str name="qf">title^1.5 content^1.0</str> <str name="rows">100</str>
<str name="fl">name,title,score</str>
<bool name="clustering">true</bool> <bool name="clustering.results">true</bool> <str name="clustering.engine">default</str>
<str name="carrot.url">name</str> <str name="carrot.title">title</str> <str name="carrot.snippet">content</str>
<!--只聚类高亮的段 --> <str name="carrot.produceSummary">true</str> <!--只分析内容中三段 --> <str name="carrot.summarySnippets">3</str> </lst>
<arr name="last-components"> <str>clustering</str> </arr> </requestHandler> |
访问
http://localhost:8983/solr/example/config1_1?q=memory&wt=xml&indent=true
5.集成solr到carrot2的网站
准备Tomcat和carrot2-webapp-3.9.2
将carrot2-webapp-3.9.2.war解压,修改F:\solr\apache-tomcat-6.0.39\webapps\carrot2-webapp-3.9.2\WEB-INF\suites中suite-webapp.xml文件
<component-suite> <sources> <source component-class="org.carrot2.source.solr.SolrDocumentSource" id="solr" attribute-sets-resource="source-solr-attributes.xml"> <label>Solr</label> <title>Solr Search Engine</title> <icon-path>icons/solr.png</icon-path> <mnemonic>s</mnemonic> <description>Solr document source queries an instance of Apache Solr search engine.</description> <example-queries> <example-query>test</example-query> <example-query>solr</example-query> </example-queries> </source> </sources> <!-- Algorithms --> <include suite="algorithm-passthrough.xml"></include> </component-suite> |
修改source-solr-attributes.xml文件
<attribute-sets default="overridden-attributes"> <attribute-set id="overridden-attributes"> <value-set> <label>overridden-attributes</label> <attribute key="SolrDocumentSource.serviceUrlBase"> <value value="http://localhost:8983/solr/example/config1_2"/> </attribute> <attribute key="SolrDocumentSource.solrSummaryFieldName"> <value value="content"/> </attribute> <attribute key="SolrDocumentSource.solrTitleFieldName"> <value value="title"/> </attribute> <attribute key="SolrDocumentSource.solrUrlFieldName"> <value value="name"/> </attribute> <!-- Proxy clusters from Solr. Link on 'name' field. --> <attribute key="SolrDocumentSource.solrIdFieldName"> <value value="name"/> </attribute> <attribute key="SolrDocumentSource.readClusters"> <value value="true"/> </attribute> </value-set> </attribute-set> </attribute-sets> |
6.启动Tomcat
将carrot2-webapp-3.9.2放到tomcat的webapps下并启动tomcat
访问地址http://localhost:8080/carrot2-webapp-3.9.2
搜索memory
