查找给定文本中的所有选定单词

Question

我有下面的代码，我希望用户输入一些关键字，然后从给定字符串中找到这些单词中存在的内容，但生成的切片是长度等于要检查的文本的空切片 playgroundmatches

package main

import (

    "fmt"

    "regexp"

)

func main() {

    p := []string{}

    p = append(p, "engineer")

    p = append(p, "doctor")

    var skills string

    for _, z := range p {

        skills += `|` + z

    }

    fmt.Println(skills)

    re := regexp.MustCompile(`(?i)` + skills)

    matches := re.FindAllString("I'm an engineer not a doctor", -1)

    fmt.Println(matches)

    for i, j := range matches {

        fmt.Println(i, j)

    }

}

package mainimport (    "fmt"    "regexp"    "strings")func main() {    p := []string{}    p = append(p, "engineer")    p = append(p, "doctor")    p = append(p, "chemical (permit)")    skills := strings.Join(p, "|")        fmt.Println(skills)    re := regexp.MustCompile(`(?i)` + skills)    matches := re.FindAllString("I'm an engineer not a doctor who is getting chemical permits", -1)    fmt.Println(matches, len(matches))    for i, j := range matches {        fmt.Println(i, j)    }}输出为：engineer|doctor|chemical (permit)[engineer doctor chemical permit] 30 engineer1 doctor2 chemical permit
