How to use the search engine's own clever search function to see the recent website situation, looking for publishing platform outside the chain, etc. Today we talk about two good search skills: 一、搜索引擎高級搜索工具 An advanced search tool and search engine 搜索引擎的高級搜索工具你用過嗎？這對于網站推廣人員來說可是個好東西。講解好處之前，我們先找到高級搜索怎么操作的，以百度為例，主要有兩種方法： The search engine's advanced search tools you used? It's a good thing for site popularization personnel. Before explaining benefits, let's find how advanced search operation, baidu, for example, there are two main methods: 1、直接進入百度首頁->設置->高級搜索; 1, direct access to baidu home page - > Settings - > advanced search; 　　 ↓↓↓ Left left left 2、輸入關鍵詞，在搜索結果頁面點擊“搜索工具”; 2, input keywords in the search results page, click on the "search tool"; 　　 ↓↓↓ Left left left 從上面的截圖我們可以看見，高級搜索中的細分做的非常的詳細，包含了不同的維度，如時間、匹配、位置、指定網站搜索等;所以SEO的小伙伴注意了，使用高級搜索的好處來了，比如： From the screenshot above we can see that in the advanced search segmentation do very detailed, contains different dimensions, such as time, matching, the location, the designated site search, etc.; So SEO friends pay attention to, the benefits of using the advanced search, such as: 1、查看自己網站的最近收錄; 1, view their website recently, included; 　　 可以對搜索結果進行時間段的選擇，比如我們在查詢收錄的時候，可以限制一段時間，一天，一周，一月等，這樣的好處能夠快速幫助我們判斷搜索引擎對于網站的收錄頻率。 Can choose time of the search results, such as when we were in a query, included, can restrict a period of time, day, week, month, etc., the benefits of this can help us quickly determine search engine for web site included the frequency. 2、過濾不想要的搜索結果; 2, filtering unwanted search results; 我們可以利用高級搜索工具對搜索結果頁面進行篩選，比如我們查詢“seo”關鍵詞，但是我們不想看出現seo外包、seo公司、seo查詢這一類的網站，此時我們就可以在限制關鍵詞中添加“外包 查詢 公司”即可;　 We can use advanced search tool to filter the search results page, for example, we query keywords "seo", but we don't want to see outsourcing seo, seo, seo company of this kind of site, at this point we can "query" outsourcing company is added in the restricted keywords; 3、快速查找需要文檔; 3, quickly find needed documents; 有時候我們經常會在網上找一些專業的文檔資料，如word，ppt，pdf等，這個時候我們也可以借助高級搜索工具快速實現，比如我們想找seo教程的pdf文檔，見圖：　 Sometimes, we often find some professional online documentation, such as word, PPT, PDF, etc., this time we can also use the advanced search tool rapid implementation, for example, we want to find seo tutorial PDF documents, as shown in figure: 二、使用高級搜索指令 Second, using the advanced search commands 其實高級搜索指令的搜索結果，大都可以通過上面所介紹的高級搜索工具完成。區別在于一個是可視化的，一個是需要輸入指令完成的。掌握一些基本的指令搜索能提高工作效率。下面就來介紹幾種在百度中常見的高級搜索指令： Actually advanced search instructions of the search results, most can be done through the introduction of the advanced search tool above. The difference is that one is visual, one is the need to input commands. Master some basic instructions search can improve the work efficiency.
