Performing indexing process of each site/page or search process in a separate thread. Developed for CS212: Software Development as part of semester long project. Learn more about bidirectional Unicode characters. This rank number changes as the pages are transversed one after another using the formula : , My personal source code search engine project. ATTENTION! DEFAULT = 60%. Using these datastructures, the engine transverses the links one by one and optimizes the best possible outcome to display to the user while transversing throw each link. The Java search engine is designed for multi-threaded indexing of a given group of sites with subsequent search by their content (Russian words). OR for or search on two words.
