09/2011 Update: Craigslist seems to change their booleans every now and then. Parenthesis and apostrophes at one point were for phrases and OR operators.
Just like the renowned Google search engine, Craigslist.org has their own technical search term operators that will alter the parameters of your search. If you are looking to add special conditions such as customizing your neighborhoods when looking for an apartment near downtown Tucson and historic districts, you could easily enter in the following into the native search bar on craigslist:
"iron horse"|"armory park"|"el encanto"|"feldmans"|"feldman's"|"Rincon Heights"|"Arizona Inn"|"Colonia Solana"|"Fourth Avenue"|"Sixth Avenue"|"6th Ave"|"4th Ave"|"west University"
If the above code doesn’t make too much sense, so I can break it down for you. The search looks at 15 distinct searches with single words, or multiple words in consecutive order.
You can make your own custom searches in Craigslist by following their rules for Boolean keys:
Anything in parentheses is treated as an exact phrase.
Vertical pipes act as an “OR” as shown in spelling the ambiguous color. This comes in handy if you want to search for multiple items at once. It can save you plenty of time.
This one uses both previous search methods and displays results from both “New York” and “New Jersey”
Macbook Air -11
Preceding a search term with a hyphen or dash will remove any search results that contain the word. In this case, any 11″ Apple computers would be omitted. This would allow you to find all other sized MacBook Air laptops and only omit “11.”
-"do not include phrase"
This one above shows that you could NOT INCLUDE an entire phrase as well.
The possibilities are practically endless. Let the search be your guide. And let craigslisters continue to buy used goods and services efficiently.
