Is there any faster way to search for a string in a file?

The Aho-Corasick string searching algorithm simultaneously finds all occurrences of multiple patterns in one pass through the text. On the other hand, the Boyer-Moore algorithm is understood to be the fastest algorithm for a single pattern.
1. Which of the following is the fastest algorithm in string matching field? Explanation: Quick search algorithm is the fastest algorithm in string matching field whereas Linear search algorithm searches for an element in an array of elements.
The comparison algorithm is Knuth Morris Pratt (KMP) and Boyer Moore (BM) algorithm. Based on previous research, the KMP algorithm has a better performance compared to other string matching algorithms.
Boyer Moore Algorithm: This algorithm uses best heurestics of Naive and KMP algorithm and starts matching from the last character of the pattern. Using the Trie data structure: It is used as an efficient information retrieval data structure.
Look at this site, where you can also see the matching time for each of the algorithms.
