找到与查询结果相似的文档:
http://localhost:8983/solr/select?q=name:edition&mlt=true&mlt.fl=name&mlt.mintf=1&mlt.mindf=1
mlt.fl:按照结果文档的哪一个field求相似。
mlt.mintf:结果文档中的本field的某一个词出现的tf大于此值,才以此词求相似。
mlt.mindf:通上,不过是df。
自定义的显示结果(非xml):
首先定义渲染器和名字:
- <queryResponseWriter name="velocity" class="org.apache.solr. request.VelocityResponseWriter"/>
- <requestHandler name="/browse" class="solr.SearchHandler">
- <lst name="defaults">
- <str name="wt">velocity</str>
- <str name="v.template">browse</str>
- <str name="v.layout">layout</str>
- <str name="title">Solr cookbook example</str>
- <str name="defType">dismax</str>
- <str name="q.alt">*:*</str>
- <str name="rows">10</str>
- <str name="fl">*,score</str>
- <str name="qf">name</str>
- </lst>
- </requestHandler>
http://localhost:8983/solr/select?q=name:book&hl=true
指定高亮显示的field:http://localhost:8983/solr/select?q=name:book&hl=true&hl.fl=name,description
指定高亮的标签:http://localhost:8983/solr/select?q=name:book&hl=true&hl.simple.pre=<b>&hl.simple.post=</b>
高亮长文本并获得好的性能:
- <field name="name" type="text" indexed="true" stored="true"
- <strong>termVectors="true" termPositions="true" termOffsets="true"</strong> />
对某些field按照函数结果进行排序:
http://localhost:8983/solr/select?q=name:company&sort=dist(2,geoX,geoY,13,13)+asc
按照发音查询:
- <field name="name" type="phonetic" indexed="true" stored="true" />
- <fieldtype name="phonetic" stored="false" indexed="true" class="solr.
- TextField" >
- <analyzer>
- <tokenizer class="solr.StandardTokenizerFactory"/>
- <filter class="solr.DoubleMetaphoneFilterFactory" inject="false"/>
- </analyzer>
- </fieldtype>
自定义忽略的词语:
- <field name="name" type="text_ignored" indexed="true" stored="true" />
- <fieldType name="text_ignored" class="solr.TextField"
- positionIncrementGap="100">
- <analyzer>
- <tokenizer class="solr.WhitespaceTokenizerFactory"/>
- <filter class="solr.StopFilterFactory" ignoreCase="true"
- words="ignored.txt" enablePositionIncrements="true" />
- </analyzer>
- </fieldType>
对查询结果计算统计:
http://localhost:8983/solr/select?q=name:book&stats=true&stats.field=price
返回结果:
- <lst name="stats">
- <lst name="stats_fields">
- <lst name="price">
- <double name="min">27.77</double>
- <double name="max">39.99</double>
- <double name="sum">97.86999999999999</double>
- <long name="count">3</long>
- <long name="missing">0</long>
- <double name="sumOfSquares">3276.9851000000003</double>
- <double name="mean">32.62333333333333</double>
- <double name="stddev">6.486118510583508</double>
- </lst>
- </lst>
- </lst>
检查拼写错误:
- <searchComponent name="<strong>spellcheck</strong>" class="solr.<strong>SpellCheckComponent</strong>">
- <lst name="spellchecker">
- <str name="name">default</str>
- <str name="field">name</str>
- <str name="spellcheckIndexDir">./<strong>spellchecker</strong></str><!-- 目录等同于索引目录-->
- <str name="buildOnCommit">true</str>
- </lst>
- </searchComponent>
- <requestHandler name="standard" class="solr.SearchHandler"
- default="true">
- <arr name="last-components">
- <str><strong>spellcheck</strong></str>
- </arr>
- </requestHandler>
http://localhost:8983/solr/spell?q=name:(other boak)&spellcheck=true&spellcheck.collate=true
- <lst name="spellcheck">
- <lst name="suggestions">
- <lst name="othar">
- <int name="numFound">1</int>
- <int name="startOffset">6</int>
- <int name="endOffset">11</int>
- <arr name="suggestion">
- <str>other</str>
- </arr>
- </lst>
- <lst name="boak">
- <int name="numFound">1</int>
- <int name="startOffset">12</int>
- <int name="endOffset">16</int>
- <arr name="suggestion">
- <str>book</str>
- </arr>
- </lst>
- <str name="collation">name:(other book)</str>
- </lst>
- </lst>
group by功能:
http://localhost:8983/solr/select?q=name:company&group=true&group.field=mainOfficeId
每个组允许的最大的文档数目:
http://localhost:8983/solr/select?q=name:company&group=true&group.field=mainOfficeId&group.limit=4.
