 The 1975 paper Efficient string matching: A aid to bibliographic search waa wax soo saarka ah. Margaret J. Corasick's PhD dissertation (1974) waa "saareyaasha data-saareyaasha ee macluumaadka dhismaha ah" - dhismaha dhismaha dhismaha dhismaha dhismaha. Dhismaha waa in ay ka mid ka mid ah Wikipedia-ka, oo ka mid ah algorithm-ka iyo Alfred Aho (hayna waa 'A' ee AWK - Aho, Weinberger, Kernighan) oo ka mid ah la mid ah Wikipedia-ka. Waxaa jira library Python oo ku yaalaa pyahocorasick oo ku yaalaa in C si loo isticmaalo wax soo saarka. Waxaan ahaysaa in ay ka mid ah xawaaraha badan oo aad version, laakiin dhismaha waa mid ka mid ah. KMP (Knuth-Morris-Pratt) waxaa loo isticmaali karaa mid ka mid ah in ay soo saarka macluumaadka ee macluumaadka macluumaadka. Basically ahocorasick for a single pattern. Mashaariiska Aho-Corasick waa in ay ku yaalaa mashaari ah - O(shahaariyo badan oo dhan). Haddii aad leedahay milyan oo ka mid ah macluumaadka, waa in aad u baahan tahay macluumaadka ah.
