Thanks!! It's clear now, sometimes the lengthNorm is the same. See the table below:
# of terms lengthNorm 1 1.0 2 .625 3 .5 4 .5 5 .4375 6 .375 7 .375 8 .3125 9 .3125 10 .3125 Is it possible to change the lengthNorm? -- View this message in context: http://lucene.472066.n3.nabble.com/WhitespaceTokenizer-and-scoring-field-length-tp2865784p2870206.html Sent from the Solr - User mailing list archive at Nabble.com.
