内容图文
1、需要在/usr/local/services/solr/solr-4.10.3/example/solr/collection1/conf的solrconfig.xml加上
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">text</str>
</lst>
<!-- 这行代码非常重要，如果没有这行，拼写检查，是不起作用的-->
<arr name="last-components">
<str>spellcheck</str>
以便spell能够生效
2、在/usr/local/services/solr/solr-4.10.3/example/solr/collection1/conf的schema.xml修改，加上字段，否则会报错
如：
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="sku" type="text_en_splitting_tight" indexed="true" stored="true" omitNorms="true"/>
<field name="name" type="text_general" indexed="true" stored="true"/>
<field name="addr" type="text_general" indexed="true" stored="true"/>
<field name="age" type="int" indexed="true" stored="true"/>
<field name="manu" type="text_general" indexed="true" stored="true" omitNorms="true"/>
