Thank you. You always with good reviews and feedbacks.

• To find similar ones, I've used the More Like This for elastic search. Most of the magic is done by elastic search, but I had to make some adjustments in the query to increase the range (https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-mlt-query.html)

• Yes Yes. I'll improve next time.

• I'm glad you enjoyed it, but I have a lot to improve on. I am even more happy to receive a message from you, I consider you one of the utopian's most demanding people, not that this is bad. Keep it up!

• Elastic Search will return error by duplicate ID, but was to update the readme and make it more practical. The collector is just for picking up old issues.

• My next update will cover all this part.

Thank you again.
