If you have a number of long queries running, your system can become CPU
bound resulting in low throughput and high response times. There are
many ways you can construct a query that will cause it to take a long

Length normalization in the Similarity class will generally favor
shorter fields. For example, with the DefaultSimilarity, the length

The norm is multiplied by the score.
I say "generally will favor" because the length norm
