# The best way to search Google more comprehensively is to click on Advanced Search.
# It allows you to search for more precise phrases, "all words," or specific keywords in the appropriate search box.
# In Advanced Search, you can still customize how many search results are displayed on a page, the language of the information you're looking for, and the file format.
# The "Search the following sites or domains" option lets you limit your search results by entering a top-level domain (e.g., .co.uk).
# You can also click the "Date, usage rights, numeric range, and more" link to access even more advanced features. (Google's Chinese version displays these options separately on the page.)
# Save your settings; most of these advanced functions can also be achieved through command-line parameters in the search box on Google's homepage.
# Google's main search function can invisibly combine Boolean structures with "AND." For example, if you type "smoke fire," it means searching for "smoke AND fire."
# To make Google search for "smoke" or "fire," simply type "smoke OR fire."
# You can also use "|" instead of "OR." For example: "smoke | fire."
# Boolean structures like "AND" and "OR" are case-sensitive and must be written in all caps.
# To search for proper nouns, enter one or several keywords enclosed in parentheses. For example: "water (smoke OR fire)."
