Hello friends,

I Would Like to know that Which algorithm is used for Keyword search?

There's crawling the web, determining the URLs and content of documents that need to be added to the index. There's extracting terms from the document content and adding the URL for the document to the index for each of those terms. There are algorithms related to handling things like multi-word terms vs documents that simply match several words. There are the algorithms and data structures necessary to store the index in a manner which can be searched quickly. There are the algorithms which provide redundancy and fault tolerance for each component in the system. There's the storage system capable of storing a data structure that is measured in petabytes, etc.
