Types

type Engine

type Engine struct {
	NegativeStorage *storage.LeveldbStorage //存储负向文档的storage
	Tokenizer       *words.Tokenizer
	NegativeCount   int //负向文档数量
}

var (
	Keys []KeyItem
	Neg  *Engine
)

func NewNegative

func NewNegative(path string, tokenizer *words.Tokenizer) *Engine

func (*Engine) AllKeys

func (e *Engine) AllKeys(docs *model.NegSearch) ([]KeyItem, error)

AllKeys 函数从负向搜索的文档中获取所有关键词并返回 Engine是调用该方法的类型 docs是指向model.NegSearch的指针，表示负向搜索的文档 返回值为一个KeyItem类型的切片和error类型

func (*Engine) BatchNegativeKeys

func (e *Engine) BatchNegativeKeys(docs *[]model.NegativeDoc) ([]string, error)

BatchNegativeKeys 函数批量处理NegativeDoc类型指针切片，将其存储在NegativeStorage中，并返回存储成功的id列表和错误信息

func (*Engine) HasNegative

func (e *Engine) HasNegative(text string) ([]KeyItem, bool, error)
