  1. Cleverdon, C.W.: On the inverse relationship of recall and precision (1972) 9.30 
    9.303573 = weight(author_ss:Cleverdon, C.W. in 1842) [ClassicSimilarity], result of:
  9.303573 = fieldWeight in 1842, product of:
    1.0 = tf(freq=1.0), with freq of:
      1.0 = termFreq=1.0
    9.303573 = idf(docFreq=10, maxDocs=44421)
    1.0 = fieldNorm(doc=1842)
