Ever had that problem when you know of the concept yet can't recall the word? Thesaurus are usually pretty poor at this task, because it's built to link individual words to each other, instead of definitions to a single word.

This solution is built from WordNet through NLTK and TextBlob. It utilizes tfidf implemented by Elasticsearch to index each word by their definitions.

# install elasticsearch via https://www.elastic.co/downloads/elasticsearch 
pip install reversedict
service elasticsearch start
python cli.py --index

Basic look up

import reversedict
reversdict.lookup('run fast')

or

python cli.py 'run fast'

Synonym boosting

python cli.py 'run fast' --synonym sprint
