Types

type ContentBased

type ContentBased struct {
	// contains filtered or unexported fields
}

func NewContentBased

func NewContentBased() *ContentBased

func (*ContentBased) AddItem

func (*ContentBased) FindItems

func (c *ContentBased) FindItems(orgID string, conditions []string) []*Item

FindItems 根据条件过滤数据 * # 查找OrgID为"org1"且包含condition1和condition2条件的项目 items := cb.FindItems("org1", []string{"condition1", "condition2"}) fmt.Println("Filtered items:", items)

# 如果需要忽略，给与-1或空切片即可 // 忽略 OrgID，仅根据 Conditions 检索 items = cb.FindItems("-1", []string{"condition1", "condition2"}) // 忽略 Conditions，仅根据 OrgID 检索 items = cb.FindItems("org1", []string{}) // 忽略 OrgID 和 Conditions，检索所有项目 items = cb.FindItems("-1", []string{})
