norm[1]=5.820766E-10
norm[2]=6.9849193E-10
norm[3]=8.1490725E-10

> ** score = 0.10003257
> ** explain
> 0.050016284 = (MATCH) product of:
>   0.15004885 = (MATCH) sum of:
>     0.15004885 = weight(f1:"note book" in 0), product of:
>       0.3911943 = queryWeight(f1:"note book"), product of:
>         0.61370564 = idf(f1: note=1 book=1)
>         0.6374299 = queryNorm
