Go语言怎么实现字符串的模糊匹配

package main

import (
    "fmt"
    "github.com/texttheater/golang-levenshtein/levenshtein"
    "strings"
)

func fuzzyMatch(text, pattern string, maxDistance int) bool {
    options := levenshtein.Options{
        MaxCost: maxDistance,
    }
    distance := levenshtein.DistanceForStrings([]rune(text), []rune(pattern), options)
    return distance <= maxDistance
}

func main() {
    text := "This is a test string for fuzzy matching."
    pattern := "test string"
    maxDistance := 2 // 允许的最大编辑距离

    if fuzzyMatch(text, pattern, maxDistance) {
        fmt.Printf("'%s' found in '%s' with max distance %d\n", pattern, text, maxDistance)
    } else {
        fmt.Printf("'%s' not found in '%s' within max distance %d\n", pattern, text, maxDistance)
    }

    // 演示大小写不敏感的匹配
    text = "This is a Test String for fuzzy matching."
    pattern = "test string"
    if fuzzyMatch(strings.ToLower(text), strings.ToLower(pattern), maxDistance) {
        fmt.Printf("'%s' found in '%s' (case-insensitive) with max distance %d\n", pattern, text, maxDistance)
    } else {
        fmt.Printf("'%s' not found in '%s' (case-insensitive) within max distance %d\n", pattern, text, maxDistance)
    }
}
