search engine in PHP?

rsepp

Does anyone know if it is possible to make a full blown search engine in PHP for searching the entire internet? And if so, how, or where can I find more information on doing that?

I don't think you quite understand the implications of what you are asking. It's not what PHP can do, but what you are asking your hardware to do. The are several hundred web pages out there - most of which are porn or junk. Even with the latest processor and the fastest hardware it would still take you months to search the entire internet for even the simplest search. You need to give more details on what you are looking for.

I think what he is looking for is an option to take a search query from a user and send that to most popular search engines and have the results dsplayed on his site with necessary credit given to the sites that gave those results alongside.... Something like the second half of www.askjeeves.com
Anyway thats what I want to do.... any ideas ???

Thanks.

If you want to run your own search engine on a subsection of the internet, I suggest you take a look at Mnogosearch (http://search.mnogo.ru). In brief: a search engine exists of three parts: The spider(which collect the url's you want in your search engine), the indexer(which grabs the content of those pages) and the search engine(containing the search algoritms). Mnogo provides the spider and the indexer, the data is stored in a mysql database. There is also a PHP frontend(for handling the search algorithm) available. I have extended this php frontend with search capabilities for synonyms and a advanced categorisation tool. You can see the result at www.com4ski.com. MOST INTERESTING OF ALL: everything is free for UNIX platform so definetly take a look at it.

sasquatch2 will search your website WITHOUT a database, and is 100% php.
