Hello @Vadiraj Rao ,
Thanks for the question. The advanced query forms like fielded search, fuzzy search, proximity search, etc are not currently supported by queryType=semantic. Only the simple query syntax is supported by queryType=semantic
The full Lucene query syntax, which supports advanced query forms, is only supported by queryType=full
Please see this Azure doc for more info:

Hope that helps
