README

Multi-String Pattern Matching algorithm.

This implementation is inspired from Aho-Corasick algorithm

Getting Started

modelA = mspm.NewModel("mspm_model_A")
patternsToSearch = strings.NewReader(words) // words is newline seperated list of words/keywords

// build mspm model with patterns
modelA.Build(patternsToSearch)

inputString := "input document where the above pattern is searched for."
document := strings.NewReader(inputString)
output, err := modelA.MultiTermMatch(document)

// output ~= [{matched_word: n_count}, ..]
