# String Fingerprint

### Description
Produces a fingerprint of all strings in a `[OBJ,STRING]` input.
Fingerprint transformation goes as follows:
- lowercase
- asciify (remove accents from letters)
- tokenize
- sort tokens
- put tokens back together

### Input
- `SOURCE [OBJ,STRING]`: a 2-column input with an object-string pair. Typically obtained with the `Extract string` block 

### Output 
- `RESULT [OBJ,STRING]`: the pairs from `SOURCE`, where the string has been modified 
- `STRINGS [STRING]`: the modified strings, without the object they were paired to

### Parameters
 
Output scores can be [aggregated](docs://score_aggregation) and/or [normalised](docs://score_normalisation).
