Overview ¶
Package trigram provides string indexing and matching.
Example ¶
package main
import (
"fmt"
"dasa.cc/x/trigram"
)
func main() {
terms := []string{"the quick", "red fox", "jumps over", "the lazy", "brown dog"}
var gs trigram.Set
gs.Index(terms...)
var m []string
var u []float64
m, u = gs.Match("bog", 0.33) // mispelled "dog"
for i, s := range m {
fmt.Printf("%.2f: %q\n", u[i], s)
}
m, u = gs.Match("the", 0.33)
for i, s := range m {
fmt.Printf("%.2f: %q\n", u[i], s)
}
}
Output: 0.50: "brown dog" 1.00: "the lazy" 1.00: "the quick"
