Che poi io sono una brava persona e ho risposto

Hi xx
On the other hand I was thinking, maybe I could read a book about ElasticSearch, like https://www.amazon.it/Learning-Elastic-Stack-visualization-Elasticsearch/dp/1789954398/ref=sr_1_1?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=elastic+search&qid=1571224122&sr=8-1
And see if there's any blocker afterwards? Like for the way I've used it in the past some in depth knowledge wasn't useful or required, if you require more then I can just read a full book about it and see if it fills the needs I have to have to do my job?
