solr的索引和查询顺序

　拜读了solr的部分源码,却急于弄明白solr的索引顺序和查询顺序,如下是探访结果.

　所有的配置都在solr/example/solr/conf/schema.xml当中.

 

<!--　如下是对text类型的处理　-->

        <!-- Case insensitive stop word removal.

          analyzers to leave a 'gap' for more accurate phrase queries.

    大致的索引顺序会是:

　1.空格..............................solr.WhitespaceTokenizerFactory

    2同义词............................solr.SynonymFilterFactory

    3过滤词...........................solr.StopFilterFactory

    4拆字..............................solr.WordDelimiterFilterFactory

    5小写过滤.....................solr.LowerCaseFilterFactory

    6关键字.........................solr.KeywordMarkerFilterFactory

    7词干抽取算法............solr.PorterStemFilterFactory

 

　大致的搜素顺序是:

 

　1.空格..............................solr.WhitespaceTokenizerFactory

    2同义词............................solr.SynonymFilterFactory

    3过滤词...........................solr.StopFilterFactory

    4拆字..............................solr.WordDelimiterFilterFactory

    5小写过滤.....................solr.LowerCaseFilterFactory

    6关键字.........................solr.KeywordMarkerFilterFactory

    7英文相近词..................solr.EnglishMinimalStemFilterFactory

    8去除重复词.................solr.RemoveDuplicatesTokenFilterFactory

 

    当然了,你可以根据自己的权重来重新分配索引和搜素顺序
