I'm running a site which allows users to create subdomains. I'd like to submit these user subdomains to search engines via sitemaps. However, according to the sitemaps protocol (and Google Webmaster Tools), a single sitemap can include URLs from a single host only. What is the best approach? At the moment I've the following structure: Sitemap index located at example.com/sitemap-index.xml that lists sitemaps for each subdomain (but located at the same host). Each subdomain has its own sitemap located at example.com/sitemap-subdomain.xml (this way the sitemap index includes URLs from a single

I would like to use the API to return all tweets that match my search query, but only tweets posted within the last five seconds. With Twitter's Search API, I can use the since_id to grab all tweets from a specific ID. However, I can't really see a good way to find the tweet ID to begin from. I'm also aware that you can use "since:" in the actual query to use a date, but you cannot enter a time. Can someone with Twitter API experience offer me any advice? Thanks for reading and your time! http://apiwiki.twitter.com/Search-API-Documentation This sounds like something you can do on your end, as

While coding JavaScript and Ajax, there is no proper documentation for this function. I searched this term using api src="http://www.google.com/jsapi" and searchControl.execute("abhilashm86"); . How is this google.setOnLoadCallback(initialize) called internally? Is this function just for a new search term when the user clears previous search and starts a new one? How exactly does google.setOnLoadCallback(initialize) get trigerred? Your initialize function will be called when your document (including the Google API) is fully loaded. So you should wrap any code that uses the API in the function

I can just drag and drop any image in google and get results. :) How is it implimented ? What is the idea behind the algorithm ? Is that image data converted to anything for search or..... no idea .. Surprisingly, we can also use Google to answer this question! What is the algorithm used by Google Search by Image It is definitely not confirmed, but I'm sure Google uses many of these techniques/ a blend of them when identifying images I think that google images uses a 3 combined algorithm detect image's deformation (by rotation, scale, illumination,...) detect by the colors detect by the visual

I want to have a search engine for my website, is any of these web search engines(like Google,yahoo,etc) provide a free service? Or I should do it by myself Andy Zend_Search_Lucene is a fully implemented and fast PHP based fulltext search engine. You'll have to index your own data but it provides a great deal of flexibility and control (search content, type, associated data to return etc). There are also implementations in many other languages. This is a better option if you are indexing products or documents, not if you want the content of your website to be searched à la Google. Maybe Google

I'd like to display some custom search results. I've looked at the JSON APIs of both Google and Microsoft (Bing). Unfortunately, Google has a limit on the amount of queries a day ($50 for a maximum of ten thousand queries). However, Bing allows an "unlimited" amount of queries a day, for free. Are there other services, like Bing's JSON API, that do not have a query limit like Google's API? A related question might be how services like Metacrawler can combine search results from several search engines, while the terms of services of these engines clearly state that these results may only be
