頭條搜索Bytespider基本流程

1、打開頭條搜索頁面https://www.toutiao.com/search/ 2、輸入關(guān)鍵詞Bytespider 3、查看搜索結(jié)果，點(diǎn)擊相關(guān)文章進(jìn)入查看 4、對(duì)文章有點(diǎn)停留時(shí)間，提高效果 5、點(diǎn)擊瀏覽其它文章，以此類推，不斷完成搜索

感謝Mr.Zhao的投稿：搜索引擎最重要的是什么?有人會(huì)說是查詢結(jié)果的準(zhǔn)確性，有人會(huì)說是查詢結(jié)果的豐富性，但其實(shí)這些都不是搜索引擎最最致命的地方。對(duì)于搜索引擎來說，最最致命的是查詢時(shí)間。試想一下，如果你在百度界面上查詢一個(gè)關(guān)鍵詞，結(jié)果需要5分鐘才能將你的查詢結(jié)果反饋給你，那結(jié)果必然是你很快的舍棄掉百度。搜索引擎為了滿足對(duì)速度苛刻的要求(現(xiàn)在商業(yè)的搜索引擎的查詢時(shí)間單位都是微秒數(shù)量級(jí)的)，所以采用緩

百度搜索引擎工作原理-4-外部投票

外部投票是指其他網(wǎng)站通過鏈接引導(dǎo)用戶來到被投票網(wǎng)站的行為。在搜索引擎的工作原理中，外部投票是非常重要的因素之一，因?yàn)樗阉饕鎸⑵湟暈槠渌W(wǎng)站對(duì)被投票網(wǎng)站的認(rèn)可和推薦。外部投票的數(shù)量和質(zhì)量對(duì)搜索引擎的排名影響非常大。如果一個(gè)網(wǎng)站擁有高質(zhì)量的外部投票，那么搜索引擎就會(huì)認(rèn)為這個(gè)網(wǎng)站是一個(gè)權(quán)威和受歡迎的網(wǎng)站，排名會(huì)相應(yīng)提高。相反，如果一個(gè)網(wǎng)站的外部投票數(shù)量和質(zhì)量很差，搜索引擎就會(huì)認(rèn)為這個(gè)網(wǎng)站不值得被推

頭條搜索Bytespider基本流程

1. 確定搜索對(duì)象：首先需要確定搜索的關(guān)鍵詞或者主題，同時(shí)要考慮搜索的范圍和時(shí)間范圍。 2. 制定搜索策略：基于搜索對(duì)象和搜索范圍，制定針對(duì)性的搜索策略，選擇合適的搜索引擎，在搜索過程中要注意細(xì)節(jié)，如設(shè)置搜索選項(xiàng)等。 3. 搜集信息：第三步就是進(jìn)行搜索，搜集相關(guān)信息，可以應(yīng)用各種搜索工具，如搜索引擎、專業(yè)數(shù)據(jù)庫、社交媒體等，搜集到的信息需要進(jìn)行分類整理，提取有用的信息，剔除無效信息。 4.

頭條搜索Bytespider基本流程

1. 抓取網(wǎng)頁每個(gè)獨(dú)立的搜索引擎都有自己的網(wǎng)頁抓取程序爬蟲（Spider）。爬蟲順著網(wǎng)頁中的超鏈接，從這個(gè)網(wǎng)站爬到另一個(gè)網(wǎng)站，通過超鏈接分析連續(xù)訪問抓取更多網(wǎng)頁。被抓取的網(wǎng)頁被稱之為網(wǎng)頁快照。由于互聯(lián)網(wǎng)中超鏈接的應(yīng)用很普遍，理論上，從一定范圍的網(wǎng)頁出發(fā)，就能搜集到絕大多數(shù)的網(wǎng)頁。2. 處理網(wǎng)頁搜索引擎抓到網(wǎng)頁后，還要做大量的預(yù)處理工作，才能提供檢索服務(wù)。其中，最重要的就是提取關(guān)鍵詞，建立索引庫和索
