cts.fitness( [node as Node] ) as Number
Summary

Usage Notes
Fitness is similar to score, except that it is bounded.
It is similar to confidence, except that it is not influenced by term IDFs.
It is an xs:float in the range of 0.0 to 1.0.
It does not include quality.
Example
const s = cts.search("dog");
for (const x of fn.subsequence(s, 1, 1) ) {
cts.fitness(x);
};
// returns the fitness of the first "dog" hit
