bool firtex::search::CBooleanScorer::next (   )  [virtual]
 

依次取一个文档进行打分

返回:
返回false表明到达结尾

实现了firtex::search::CScorer。

count_t firtex::search::CBooleanScorer::nextDocs (   )  [virtual]
 

提取下一批文档

返回:
提取成功返回true，已经提取完毕返回false

实现了firtex::search::CScorer。

score_t firtex::search::CBooleanScorer::score (   )  [virtual]
 

实现了firtex::search::CScorer。

count_t firtex::search::CBooleanScorer::scores (  docid_t *&  docs,
score_t *&  scores
)  [virtual]
 

取文档的打分结果,必须配合nextDocs()使用，当返回值>0时才有效。

参数:
docs 存放文档id，docs地址由内部维护
scores 存放文档打分结果，scores地址由内部维护
返回:
打分的文档总数

实现了firtex::search::CScorer。

bool firtex::search::CBooleanScorer::skipTo (  docid_t  target,
docid_t &  nearTarget

移动到第一个文档编号大于或等于target的位置，一般配合score()使用

参数:
target 目标文档编号
nearTarget 当搜索成功时nearTarget=target,否则，返回大于target并且与target最接近的doc id, 如果target大于所有值则返回小于target且与target最接近的doc id
返回:
仅当存在这样的文档编号时返回true

实现了firtex::search::CScorer。
