如何搜索词干匹配？

即目前我有许多文件在item_title字段中包含"滑板"一词,但只有3个文件包含"滑板"一词.因此,当我进行以下搜索时:

POST /my_index/my_type/_search
{
    "size": 100,
    "query" : {
        "multi_match": {
           "query": "skateboards",
           "fields": [ "item_title^3" ]
        }
    }
}

我只得到3个结果.但是,我还希望返回带有"滑板"一词的文件.

根据我对Elasticsearch的理解,我希望通过在item_title包含分析器的字段上指定映射来完成此操作,该分析器对每个单词的词干版本进行索引,但我似乎无法找到有关如何执行此操作的文档,表明它是以不同的方式完成的.

建议？

我曾经stem_graphic绘制过茎叶图并将其保存为 pdf 但在尝试输入标题时出现错误：Figure object have no attribute set_title.

ax, b=stem_graphic(mileage['disp'])
ax.set_title("Vicky")


This is the error
Traceback (most recent call last):
File "<pyshell#214>", line 1, in <module>
ax.set_title("Vicky")
AttributeError: 'Figure' object has no attribute 'set_title'

我正在尝试从Stem项目中获取To Love With Toto乐队。

from io import StringIO

我试过这个例子:

  try:
    controller = Controller.from_port()
  except stem.SocketError as exc:

    sys.exit(1)

  try:

    pw = getpass.getpass("Controller password: ")

    try:

我正在使用一个使用Tor的刮刀,在这个示例项目中有一个简化版本:https://github.com/khpeek/scraper-compose.该项目具有以下(简化)结构:

我正在尝试使用stem python库从远程机器连接到tor的控制端口（9051）。

from stem import Signal
from stem.control import Controller


def set_new_ip():
    """Change IP using TOR"""
    with Controller.from_port(address = '10.130.8.169', port=9051) as controller:
        controller.authenticate(password='password')
            controller.signal(Signal.NEWNYM)
set_new_ip()

我收到以下错误

Traceback (most recent call last):
  File "/home/jkl/anaconda3/lib/python3.5/site-packages/stem/socket.py", line 398, in _make_socket
    control_socket.connect((self._control_addr, self._control_port))

During handling of the above exception, another exception occurred:

我目前正在使用以下设置来更改 Mac OS X 中的 IP 地址：

from stem import Signal
from stem.control import Controller

with Controller.from_port(port = 9051) as controller:
    controller.authenticate()
    controller.signal(Signal.NEWNYM)

headers = {
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:61.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.1'
}

proxies = {
    "http": "http://127.0.0.1:8118"
}

r_ip = requests.get("http://icanhazip.com", proxies=proxies, headers=headers_tor)
print(r_ip.text)

我首先在命令行中运行 Tor，然后执行上面的命令。我注意到 IP 地址不会立即更改，而是需要几秒钟才能运行上面的代码块以生成新的 IP 地址。此外，在我运行 Tor 的终端页面上，它输出如下消息：

Aug 25 04:13:53.000 [notice] Rate limiting NEWNYM request: delaying by 7 second(s)

有没有办法在没有延迟的情况下更改IP地址？

在如何在 matplolib 中制作更粗的干线中，描述了如何控制干线的宽度。但是如何控制词干标记的大小呢？

当我从词干文档中运行[example] [1]时，出现错误：

OSError: Process terminated: Failed to bind one of the listener ports.

我正在运行的确切代码如下：

import socks
import socket
import stem.process
import urllib

from stem.util import term

SOCKS_PORT = 7000

# Set socks proxy and wrap the urllib module

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', SOCKS_PORT)
socket.socket = socks.socksocket

# Perform DNS resolution through the socket

def getaddrinfo(*args):
  return [(socket.AF_INET, socket.SOCK_STREAM, 6, '', (args[0], args[1]))]

socket.getaddrinfo = getaddrinfo

def query(url):
    return urllib.urlopen(url).read()

def print_bootstrap_lines(line):
  if "Bootstrapped " in line:
    print(term.format(line, term.Color.BLUE))

print(term.format("Starting Tor:\n", term.Attr.BOLD))

tor_process …

我想在使用时在python中制作更粗的干线plt.stem.

这是我的代码

import matplotlib.pyplot as plt
import numpy as np

N = 20

n = np.arange(0, 2*N, 1)

x = np.exp(-n/N)*np.exp(1j * 2*np.pi/N*n)

plt.stem(n,x.real) 

plt.show()

我改变了plt.stem(n,x.real,linewidth=10),但没有改变.有没有函数来设置linewidth的plt.stem？

我安装了Tor作为我的Windows机器上的服务运行,我试图通过Stem包在python中发出请求.在我的torrc文件中,我将ControlPort指定为9051并设置了HashedControlPassword.当我运行netstat时,我看到Tor在localhost:9050上运行,但没有任何东西正在侦听端口9051.因此,当我尝试连接到python中的ControlPort时:

Controller.from_port(port=9051)

结果是

[Errno 10061] No connection could be made because the target machine actively refused it

我尝试重新启动服务,我甚至重新安装了Tor浏览器,但似乎没有什么能让ControlPort工作.
