Corrected values in "Putting it Together" Example

The calculated values of the idf and fieldnorm were wrong according to the formulas given earlier in the document.  I don't know whether this represents an error in the formulas, the setup of the example, or the calculations, but it is confusing for someone trying to learn es.

My Reasoning:
idf(docFreq=1, maxDocs=1) 
    = 1 + log ( numDocs / (docFreq + 1))     #Quoted from earlier in document
    = 1 + log( maxDocs / (docFreq + 1)       #Since maxDocs is the same as numDocs in this example, right?
    = 1 + log( 1 / (1 + 1))                            #plugging in the values
    = 1 + log( 1/2)                                      
    = 1 + (-0.30102999566)                         #https://www.google.com/search?q=log%280.5%29&ie=utf-8&oe=utf-8#q=log%281%2F2%29
    = 0.69897000                                       #rounded to 8 digits as in the current document

The number in the original document (0.30102999566) is the log(2). Maybe they flipped numDocs and docFreq and then forgot to add 1?  idk.

fieldNorm(doc=0) 
    = 1 / sqrt(numTerms)    #Quoted from earlier in document
    = 1 / sqrt(3)                 #There are 3 terms: "quick", "brown", and "fox"
    = 1 / 1.73205080757    #https://www.google.com/search?q=sqrt%283%29&ie=utf-8&oe=utf-8
    = 0.57735027              #rounded to 8 digits to match idf precision

Perhaps there were supposed to be four terms in the example or perhaps the formula was supposed to be 1 / sqrt( 1 + numTerms ).  Again, idk.
