- If the document has the concrete criteria value, and the number of documents contain the concrete criteria value is above 1 then we will give 1 score otherwise 0 to the document in the criteria row. 如果文档中包含一个具体的条件值, 我们需要在统计表中观察该值所对应的文档数目是否大于1,如果是的话我们就给该文档在该条件行上为1否则就为0. For examples:
document sets:

document B:{telephone no : 23456, email : C@A.com} type |_Doc A_________Doc B
