You need to bind a callback function to a mouse event:

import Tkinter as tk

def clear_search(event):
    search.delete(0, tk.END)

root = tk.Tk()

search = tk.Entry(root, width=100)
search.insert(0, "Enter the value to search")
search.pack()
search.bind("<Button-1>", clear_search)

root.mainloop()

This will always clear the Entry; you probably want to check if it contains 
the initial message first to avoid that the user accidentally loses input.
