Hi Franck, There are two issues here. First the completion suggester is not based on n-grams but on a FST, so you should not use a n-gram tokenizer. Another thing to know is that the completion suggester is a prefix suggester, not an infix suggester, meaning that it can only suggest from the beginning of the input, yet you don't have any input that starts with "Munich". The only way to make it recommend hotels based in Munich would be to add more inputs to your documents that start with "Munich".
