Azure Cognitive Search - No results using wildcards on content with DOT

Question

I'm using Azure Cognitive Search to build a rich search experience inside a web application, however I'm facing the following issue: a field of the index will contains codes like "Z.A.01.12", "A.A.44.11" and so on...I'm trying to use the wildcards * as suffix in order to search all the results that starts with the value Z.A (just an example).

"Z.A.01.12" -> Z.A* => No results found. 
"Z.A.01.12" -> Z.A.* => No results found. 
"Z.A.01.12" -> Z\.A* => No results found. 

I have tried different analyzer (standard lucene, en.microsoft, whitespace and keyword), but also when I see that exists only one token produced (for example with whitespace) with the entire content, when I query the service using wildlcard I receive "No results found". I have already set queryType=full and searchMode=any. Furthermore I also tried to escape the . with "", but the results is always empty. Is there anything I can do to manage these cases?
