-// Size, in bytes, of the bloom filter index for bigrams
-// 128 gives us 1024 buckets. The probability of false positive is (1 - e ** (-kn/m))**k,

-// bits we can test.
-// At the moment 100 is the maximum number of bigrams for a word with the current
-// dictionaries, so n = 100. 1024 buckets give us m = 1024.
-// With 1 hash function, our false positive rate is about 9.3%, which should be enough for
-// our uses since we are only using this to increase average performance. For the record,
-// k = 2 gives 3.1% and k = 3 gives 1.6%. With k = 1, making m = 2048 gives 4.8%,
