Lucene会在Index time把索引字段的所有词项切分计算出来,并按照字典序生成一个词项字典(Term Dictionary),此项字段存储的是去重了之后的所有词项。查询时有效组成的部分包括term dictionary(最终生成的词项词典)和倒排表(Posting List),它保存的就是包含所有当前词项的元数据的 id 的有序 int 数组。 2.) 倒序索引的...

根据关键词建立倒排索引。倒排索引包括Term Index(单词索引),Term Dictionary(单词字典),Posting List(倒排列表) 用户输入关键词进行搜索。 倒排索引具体组成 单词词典(Term Dictionary):包含了所有数据在进行分词之后生成的单词(term),词典是由所有term构成的字符串集合。搜索引擎的通常索引单位是term,词典内每条索引项记...
