1、关于默认搜索域
If you are using the Lucene query parser,queries that don't specify a field name will use the defaultSearchField. The DisMax and Extended DisMax query parsers do not use this value.
Use of the defaultSearchField element is deprecated in Solr versions 3.6 and higher. Instead,you should use the df request parameter. At some point,the defaultSearchField element may be removed。
即使用solrConfig中的df属性代替schema中的
defaultSearchField。
2、关于qf
从solr的example中得到的solrConfig.xml中，qf的定义如下：
<str name="qf">
text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
title^10.0 description^5.0 keywords^5.0 author^2.0 resourcename^1.0
</str>由于content不占任何的权重，因此如果某个文档只在content中包含关键字的话，搜索结果并不会返回这个文档。因此，对于nutch提取的索引来说，要增加content的权重，以及url的权重（如果需要的话）：
<str name="qf">
content^1.0 text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
title^10.0 description^5.0 keywords^5.0 author^2.0 resourcename^1.0
</str>
二、Search Handler
- <requestHandlername="/browse"class="solr.SearchHandler">
- lstname="defaults">
- strname="echoParams">explicit</str
- <!--VelocityResponseWritersettings-->
- strname="wt">velocitystrname="v.template">browsestrname="v.layout">layoutstrname="title">Solritas_test<!--Querysettings-->

1、SearchHandler是reqestHandler中的一种，它以requestHandler作为顶层元素。 @H_403_921@ 2、二级元素包括first-components,last-components,defautls等。 @H_403_921@ 3、Velocity的配置 @H_403_921@
