成员函数文档

void firtex::search::CBooleanQuery::add ( CBooleanClause * pClause )

void firtex::search::CBooleanQuery::add ( CQuery * query,

const bool required,

const bool prohibited

)

添加查询
参数:

required 该查询是否必须匹配

prohibited 匹配该查询的文档必须排除

void firtex::search::CBooleanQuery::clear ( )

CQuery* firtex::search::CBooleanQuery::clone ( ) [virtual]

克隆新的对象,需子类实现非内部对象,外部删除
实现了firtex::search::CQuery。

CWeight* firtex::search::CBooleanQuery::createWeight ( CSearcher * pSearcher ) [protected, virtual]

创建Query对应的Weight
返回:
Weight对象指针，该对象一般由外部调用create的对象销废

重载firtex::search::CQuery。

int32_t firtex::search::CBooleanQuery::getClaouseCount ( ) [inline]

const char* firtex::search::CBooleanQuery::getClassName ( ) [inline, static]

int firtex::search::CBooleanQuery::getMaxClauseCount ( ) [static]

const char* firtex::search::CBooleanQuery::getQueryName ( ) const [inline, virtual]

获取查询名称标识
实现了firtex::search::CQuery。

CQuery* firtex::search::CBooleanQuery::optimize ( firtex::index::CIndexReader * pReader ) [virtual]

对查询进行优化,生成新的查询对象,子类可重载,默认情况下返回自身
参数:

pReader 用于访问索引

返回:
优化后的新的查询对象,默认情况下返回自身非内部对象,外部需要删除

重载firtex::search::CQuery。

CScorer* firtex::search::CBooleanQuery::scorer ( CSearcher * pSearcher ) [virtual]

返回打分器,需子类实现
参数:

pSearcher 索引搜索器非内部对象,外部删除

重载firtex::search::CQuery。
