Getting more search results per page via URL

北城以北 提交于 2019-12-05 23:18:17
问题 I've been writing a program which extracts data from web searches. To get more data, I'd ideally like to extract more results per query through a script (let's say 100 or so). My question is, is there a way to modify the URL for Google, Yahoo, or Bing (preference in that order) so that I can get more than 10 results per query? For Google, appending &num=99 used to work at one point but no longer works :( I saw a similar append of &count=50 but that didn't work on any of the search engines

Implementing a site search engine that searches static pages

这一生的挚爱 提交于 2019-12-05 23:05:22
What I would like to accomplish is to integrate a search feature into my website that is capable of searching my web pages that are static(content does not change). I need the search engine to be free to use and must operate using JavaScript or PHP (and MySQL if needed). I have tried looking on Google (if anyone is wondering) , but maybe I'm just not searching for the right thing. If anyone could point me in the right direction I would greatly appreciate it. Thanks Why reinvent the wheel - use Google Custom Search: http://www.google.com/cse/ i got something today , so updating for other users

Where do search engines start crawling?

99封情书 提交于 2019-12-05 13:57:27
问题 What do search engine bots use as a starting point? Is it DNS look-up or do they start with some fixed list of well-know sites? Any guesses or suggestions? 回答1: Your question can be interpreted in two ways: Are you asking where search engines start their crawl from in general, or where they start to crawl a particular site? I don't know how the big players work; but if you were to make your own search engine you'd probably seed it with popular portal sites. DMOZ.org seems to be a popular

Set input field focus on start typing

三世轮回 提交于 2019-12-05 13:56:20
I am looking for a way to be able to start typing on a website without having selected anything and then have a specific input field in focus. Google also employs this feature. In their search results you can click anywhere (defocus the search field) and when you start typing it automatically focuses on the search field again. I was thinking about jQuery general onkeyup function to focus on the field, any suggestions? Much appreciated. You should bind the keydown event, but unbind it immediately so that typing may continue in other text inputs without reverting focus to the default input. $

is there any link to show all public repositories in GitHub?

ぐ巨炮叔叔 提交于 2019-12-05 13:35:17
Yesterday, I was trying to get a list of all public repositories in GitHub, but I didn't find any link. And for example in Sourceforge you can list all proyects by categories or in Google code you can search all for all proyects. Yes, I tried to search with keywords like as "*" or "%" or empty string, but you only see this page https://github.com/search?q=&type=Everything&repo=&langOverride=&start_value=1 You can list all repositories in github using the following request: https://api.github.com/repositories?since=0 it will return the first "n" repositories of id>0 as a JSON Array. You should

How to Google for --depend?

被刻印的时光 ゝ 提交于 2019-12-05 10:09:44
The latest makefiles we've received from a third party vendor contain rules with --depend on the end of build rules, so I thought I would look it up on Google, but try as I might, I can't persuade it to display any pages with exactly the characters --depend I've tried surrounding it with quotes "--depend": I've tried the Advanced Search: I've tried backslashes "\-\-depend" in the (vain) hope that there is some sort of unpublished regular expression search available. Am I missing something blindingly obvious? Please note that this is NOT a question about what --depend does, I know that, it's a

How does pageranking algorithm deal with webpage without outbound links?

[亡魂溺海] 提交于 2019-12-05 08:27:45
I am learning about the PageRanking algorithm so sorry for some newbie questions. I understand that the PR value is calculated for each page by the summation of incoming links to itself. Now I am bothered by a statement which stated that "the PageRank values sum to one " at wikipedia . As the example shown at wikipedia, if every page has a outbound link, then the summation of whole probabilities from each page should be one. However, if a page does not have any outbound link such as page A at the example, then the summation should not be value 1 right ? Thus, does Pagerank algorithm have to

robots.txt allow all except few sub-directories

点点圈 提交于 2019-12-05 07:52:28
I want my site to be indexed in search engines except few sub-directories. Following are my robots.txt settings: robots.txt in the root directory User-agent: * Allow: / Separate robots.txt in the sub-directory (to be excluded) User-agent: * Disallow: / Is it the correct way or the root directory rule will override the sub-directory rule? unor No, this is wrong. You can’t have a robots.txt in a sub-directory. Your robots.txt must be placed in the document root of your host. If you want to disallow crawling of URLs whose paths begin with /foo , use this record in your robots.txt ( http://example

Replace all occurences of string in multiple source files in Intellij

浪尽此生 提交于 2019-12-05 06:50:45
Is it possible? 2 options is preferable : 1) with variable 2) other string. Thanks. Yes, it's possible. The command is named "Replace in path" (Ctrl-Shift-R in my keyboard shortcut preferences). You could have found it yourself by typing Ctrl-shift-A, and typing "replace": this will list all the commands containing the word "replace" in their name. 来源: https://stackoverflow.com/questions/21086759/replace-all-occurences-of-string-in-multiple-source-files-in-intellij
