similarity as alternative way of searching
Problem Provide a command to search by similarity, according to different well known algorithms such as Levenshtein, Cosine, Jaccard.
Solution In practice, create a tiny wrapper around this library: https://github.com/tdebatty/java-string-similarity
Normalized values would require also a new value type (decimal or float).
Benefit Being able to search not only by exact match or regexp but also by similarity.
Smart synonym search would also be magnificent. Some embedding like Word2Vec or more modern from GPT-2. I'd love play around with them.
Look, lots of guys play with them for fun, pre-training those enormous models on some specific area. Ask them to train a model on bash scripts and comments. It will then write code for you, from the comments :-)
