You can use the folowing methods to extract relevant tags from documents:

var testText = "This text is from a Wikipedia entry about Bayes' Theorem. Bayesian inference has applications in artificial intelligence and expert systems. Bayesian inference techniques have been a fundamental part of computerized pattern recognition techniques since the late 1950s. There is also an ever growing connection between Bayesian methods and simulation-based Monte Carlo techniques since complex models cannot be processed in closed form by a Bayesian analysis, while the graphical model structure inherent to statistical models, may allow for efficient simulation algorithms like the Gibbs sampling and other Metropolis-Hastings algorithm schemes. Recently Bayesian inference has gained popularity amongst the phylogenetics community for these reasons; applications such as BEAST, MrBayes and P4 allow many demographic and evolutionary parameters to be estimated simultaneously."

var tags = autoTagger

// using portuguese stop words
.useStopWords('pt')

// using english stop words
.useStopWords('en')

// adding aditionals stop words
.useStopWords(['will'])

// extract tags from text
// return tags that have at least 2 ocurrences
// and look for ocurrences of 4 consecutive words 
.fromText(testText,2,4);

console.log(tags);
