Custom Encoder
----------------
// Split a passed string into an Array of words:
function englishEncoder(string){
return string.toLowerCase().split(/[^a-z]+/)
}
// For CJK split a passed string into an Array of chars:
function chineseEncoder(string){
return string.replace(/\s+/, "").split("")
}
// Alternatively do not split the input:
function fixedEncoder(string){
return [string]
}
Built-in Encoder (Workflow)
----------------------------
Pipeline:
1. apply this.normalize: charset normalization:
applied on the whole input string e.g. lowercase,
will also apply on: filter, matcher, stemmer, mapper
2. apply this.split: split input into terms (includes/excludes)
3. apply this.filter (pre-filter)
4. apply this.matcher (replace terms)
5. apply this.stemmer (replace term endings)
6. apply this.filter (post-filter)
7. apply this.mapper (replace chars)
8. apply this.replacer (custom regex)
9. apply this.dedupe (letter deduplication)
10. apply this.finalize
