Question

我使用的是elasticsearch 2x版本

我想在字段中使用不同的值。我在查询中只获得10个值。如何更改此选项以查看所有不同的记录？

以下是我正在使用的查询：

GET messages-2017.04*/_search
{
    "fields": ["_index"],
    "query": {
        "bool": {
            "must":{
                "bool":{
                "should": [
                        {
                            "match": {
                                "RouteData": {
                                    "query": "Q25B",
                                    "type": "phrase"
                                }
                           }
                        }
                    ]
               }
            }
        }
    }
}

我需要从数据库中获取所有不同的_index名称。

您需要使用Toplevel聚合，如下所示：

#!/usr/bin/env python3.6
# encoding: utf-8

import tkinter as tk
import tkinter.font
from tkinter import ttk


class baseApp(ttk.Frame):
    """
    Parent classe for main app window (will include some aditional methods and properties).
    """
    def __init__(self, master, *args, **kwargs):
        super().__init__(master, *args, **kwargs)
        self.master = master
        self.mainframe = ttk.Frame(master)
        self.mainframe.pack()


class App(baseApp):
    """ Base class for the main application window """
    def __init__(self, master, *args, **kwargs):
        super().__init__(master, *args, **kwargs)
        self.master = master
        self.lbl_text = ttk.Label(self.mainframe, text="This is the Main Window")
        self.lbl_text.pack()
        self.btn = ttk.Button(self.mainframe, text="Open Second window",
                              command=lambda: self.create_detail_window(self, number=0))
        self.btn.pack()
        self.newDetailsWindow = {}
        self.windows_count=0

    def create_detail_window(self, *event, number=None):
        self.windows_count+=1
        self.newDetailsWindow[self.windows_count]=tk.Toplevel(self.master)
        self.newDetailsWindow[self.windows_count].geometry('900x600+80+130')
        self.newDetailsWindow[self.windows_count].title(f'Detail: {self.windows_count}')

        self.newDetailsWindow[self.windows_count].wm_protocol("WM_DELETE_WINDOW", self.newDetailsWindow[self.windows_count].destroy)
        #self.newDetailsWindow[self.windows_count].bind("Command-w", lambda event: self.newDetailsWindow[-1].destroy())

        self.detail_window = detailWindow(self.newDetailsWindow[self.windows_count], self.windows_count)
        self.newDetailsWindow[self.windows_count].focus()
        print(self.newDetailsWindow)

    def close_detail_window(self, *event):
        """ will test for some condition before closing, save if necessary and
            then call destroy()
        """
        pass
        #self.newDetailsWindow.destroy() # Shouldn't this be enough to close the secondary window?...


class detailWindow(ttk.Frame):
    """ Base class for secondary windows """
    def __init__(self, master, rep_num, *args,**kwargs):
        super().__init__(master,*args,**kwargs)
        self.num_rep = rep_num
        self.master.minsize(900, 600)
        self.master.maxsize(900, 600)
        print(f"Showing details about nr. {self.num_rep}")
        self.mainframe = ttk.Frame(master)
        self.mainframe.pack()

        self.lbl_text = ttk.Label(self.mainframe,
                                  text=f"Showing details about nr. {self.num_rep}")
        self.lbl_text.pack()


if __name__ == "__main__":
    root = tk.Tk()
    janela_principal = App(root)
    root.title('Main Window')
    root.bind_all("<Mod2-q>", exit)
    root.mainloop()
