用go语言怎么完成图书管理信息系统程序功能：参考学生管理系统对象改变为图书即可。扩展：1、实际应用价值2、检索算法实现怎么用代码实现

由于题目比较抽象，我假设这是一个简单的图书借阅管理系统，下面给出一个示例程序，实现基本的增加、删除、查询、借阅、归还等功能。

package main
 
import (
    "fmt"
)
 
type Book struct {
    id int
    name string
    author string
    borrowed bool
}
 
var books []Book
 
func main() {
    for {
        var op int
        fmt.Println("1. Add a book")
        fmt.Println("2. Delete a book")
        fmt.Println("3. Search for a book")
        fmt.Println("4. Borrow a book")
        fmt.Println("5. Return a book")
        fmt.Println("6. List all books")
        fmt.Println("7. Exit")
        fmt.Print("Please select an operation: ")
        fmt.Scanln(&op)
        switch op {
        case 1:
            addBook()
        case 2:
            deleteBook()
        case 3:
            searchBook()
        case 4:
            borrowBook()
        case 5:
            returnBook()
        case 6:
            listBooks()
        case 7:
            fmt.Println("Goodbye!")
            return
        default:
            fmt.Println("Invalid operation!")
        }
    }
}
 
func addBook() {
    var book Book
    fmt.Print("Please enter book id: ")
    fmt.Scanln(&book.id)
    fmt.Print("Please enter book name: ")
    fmt.Scanln(&book.name)
    fmt.Print("Please enter book author: ")
    fmt.Scanln(&book.author)
    book.borrowed = false
    books = append(books, book)
    fmt.Println("Book added successfully!")
}
 
func deleteBook() {
    var id int
    fmt.Print("Please enter book id: ")
    fmt.Scanln(&id)
    for i, book := range books {
        if book.id == id {
            books = append(books[:i], books[i+1:]...)
            fmt.Println("Book deleted successfully!")
            return
        }
    }
    fmt.Println("Book not found!")
}
 
func searchBook() {
    var keyword string
    fmt.Print("Please enter keyword: ")
    fmt.Scanln(&keyword)
    found := false
    for _, book := range books {
        if book.name == keyword || book.author == keyword {
            fmt.Printf("Book id: %d, name: %s, author: %s, borrowed: %t\n", book.id, book.name, book.author, book.borrowed)
            found = true
        }
    }
    if !found {
        fmt.Println("Book not found!")
    }
}
 
func borrowBook() {
    var id int
    fmt.Print("Please enter book id: ")
    fmt.Scanln(&id)
    for i, book := range books {
        if book.id == id {
            if book.borrowed {
                fmt.Println("Book already borrowed!")
            } else {
                books[i].borrowed = true
                fmt.Println("Book borrowed successfully!")
            }
            return
        }
    }
    fmt.Println("Book not found!")
}
 
func returnBook() {
    var id int
    fmt.Print("Please enter book id: ")
    fmt.Scanln(&id)
    for i, book := range books {
        if book.id == id {
            if !book.borrowed {
                fmt.Println("Book already returned!")
            } else {
                books[i].borrowed = false
                fmt.Println("Book returned successfully!")
            }
            return
        }
    }
    fmt.Println("Book not found!")
}
 
func listBooks() {
    for _, book := range books {
        fmt.Printf("Book id: %d, name: %s, author: %s, borrowed: %t\n", book.id, book.name, book.author, book.borrowed)
    }
}

这个程序实现了基本的增加、删除、查询、借阅、归还等功能，可以作为一个简单的图书借阅管理系统来使用。其中，borrowed字段表示该书是否被借阅，如果被借阅，则为true，否则为false。

至于检索算法的实现，这个需要根据具体的需求来决定，比如可以使用二分查找、哈希表、Trie树等算法来实现不同的检索功能
