4/27/2012 · Look up Ukkonen's algorithm which builds it in O(n). Also look up the Rabin-Karp algorithm which basically hashes the pattern and compares it with the hash of the search string. Using a rolling hash you can compute the hash as you move along the search string. If the hashes match only then you may compare the strings.

In computer science, the Boyer–Moore string-search algorithm is an efficient string-searching algorithm that is the standard benchmark for practical string-search literature. It was developed by Robert S. Boyer and J Strother Moore in 1977. The algorithm preprocesses the string being searched for (the pattern), but not the string being searched in (the text).
