Hint: to search for an exact phrase, put your search terms in quotation marks. For example, searching "international tax update" will show only results with that exact phrase.
To replicate the AND Boolean function, you can use two phrases inside quotation marks. For example, searching "international tax update" "thin capitalisation" will show only results containing both of those phrases.
To exclude a search term, use a minus symbol before it. For example, superannuation -contributions will show results containing the term superannuation but not contributions.
