Boolean operators

Do you use Boolean operators?

"Boolean operators are words and symbols, such as AND or NOT, that let you expand or narrow your search parameters when using a database or search engine. When you search using these operators, it is known as a Boolean search.

You can use Boolean operators such as AND, OR, and NOT alongside keywords to create a Boolean string that will refine your search to find the most relevant results and sources."

I imagine they are generally very effective when used correctly to aid with research purposes.

Back when search engines started Boolean operators were spelled in caps.
I'm not sure when they switched to symbols, but since the standard mathematical symbols like or "." were in use or escaped characters they had to use weird ones.

OR is now "|" (pipe/vbar), but they never chose a symbol for XOR

Only when designing digital logic circuits.
