One of the most popular advanced search feature is phrase search. Google and other search engines let you find web pages that include the exact phrase you type. "By putting double quotes around a set of words, you are telling Google to consider the exact words in that exact order without any change," mentions Google's help center.
The nice thing about phrase search was that you didn't have to close the quotes. You could type ["Dual Polarization Antenna] and Google assumed that you forgot to close the quotes. This was especially useful if you changed your query by adding new words or if you typed the query using a virtual keyboard.
Unfortunately, the trick no longer works and you now have to close the quotes to use phrase search:
At some point, you could even enter queries like [Dual-Polarization-Antenna] and Google returned the same results as if you typed ["Dual Polarization Antenna"].
Search is a Jack of all trades
