在搜索过程中，如果我们每次请求中都传入很多固定的参数，会很繁琐，这里再solrconfig.xml中初始化定义一些不经常改动的搜索参数：
<requestHandler name="/select" class="solr.SearchHandler"> <lst name="defaults"> <str name="echoParams">explicit</str> <!-- Query settings --> <str name="defType">edismax</str> <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> <str name="df">text</str> <str name="mm">100%</str> <str name="q.alt">*:*</str> <str name="rows">10</str> <str name="fl">*,score</str> <str name="mlt.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> <str name="mlt.fl">text,features,name,sku,id,manu,cat,title,description,keywords,author,resourcename</str> <int name="mlt.count">3</int> <!-- Faceting defaults --> <str name="facet">on</str> <str name="facet.field">cat</str> <str name="facet.field">manu_exact</str> <str name="facet.field">content_type</str> <str name="facet.field">author_s</str> <str name="facet.query">ipod</str> <str name="facet.query">GB</str> <str name="facet.mincount">1</str> <str name="facet.pivot">cat,inStock</str> <str name="facet.range.other">after</str> <str name="facet.range">price</str> <int name="f.price.facet.range.start">0</int> <int name="f.price.facet.range.end">600</int> <int name="f.price.facet.range.gap">50</int> <str name="facet.range">popularity</str> <int name="f.popularity.facet.range.start">0</int> <int name="f.popularity.facet.range.end">10</int> <int name="f.popularity.facet.range.gap">3</int> <str name="facet.range">manufacturedate_dt</str> <str name="f.manufacturedate_dt.facet.range.start">NOW/YEAR-10YEARS</str> <str name="f.manufacturedate_dt.facet.range.end">NOW</str> <str name="f.manufacturedate_dt.facet.range.gap">+1YEAR</str> <str name="f.manufacturedate_dt.facet.range.other">before</str> <str name="f.manufacturedate_dt.facet.range.other">after</str> <!-- Highlighting defaults --> <str name="hl">on</str> <str name="hl.fl">content features title name</str> <str name="hl.encoder">html</str> <str name="hl.simple.pre"><b></str> <str name="hl.simple.post"></b></str> <str name="f.title.hl.fragsize">0</str> <str name="f.title.hl.alternateField">title</str> <str name="f.name.hl.fragsize">0</str> <str name="f.name.hl.alternateField">name</str> <str name="f.content.hl.snippets">3</str> <str name="f.content.hl.fragsize">200</str> <str name="f.content.hl.alternateField">content</str> <str name="f.content.hl.maxAlternateFieldLength">750</str> <!-- Spell checking defaults --> <str name="spellcheck">on</str> <str name="spellcheck.extendedResults">false</str> <str name="spellcheck.count">5</str> <str name="spellcheck.alternativeTermCount">2</str> <str name="spellcheck.maxResultsForSuggest">5</str> <str name="spellcheck.collate">true</str> <str name="spellcheck.collateExtendedResults">true</str> <str name="spellcheck.maxCollationTries">5</str> <str name="spellcheck.maxCollations">3</str> </lst> <!-- append spellchecking to our list of components --> <arr name="last-components"> <str>spellcheck</str> </arr> </requestHandler>
其中：
score desc，指按记分降序排序。 q=myField:Java AND otherField:developerWorks; date asc此查询搜索指定的两个字段并根据一个日期字段对结果进行排序。Field 集。默认为 “*”，指所有的字段。“score” 指还应返回记分。例如 *,scorehight:
hl-highlight，h1=true，表示采用高亮。可以用h1.fl=field1,field2 来设定高亮显示的字段。
这些值都可以在select中加入，也可以用solrj的api去设定，也可以配置在solrconfig.xml中配置。
