Search Operators
- Specify words separated by space(s) to search posts containing all the words.
- Quote a string containing space(s) by double quotes to search posts which contain phrase(s) consisted of those words only in the order.
- Insert an asterisk (*) in a word without any space to search posts which contain the word(s) regardless of what the part of the asterisk is.
- Prepend a minus sign (-) without any space to a word to search posts which do not contain the word(s).
- Specify two words separated by ” OR ” in upper case to search posts which contain either of words or both. This takes precedence over words separated by space(s) only.
- You can combine the above expression. Use a pair of parenthesis to group expressions if needed.
It searches in the bodies and titles of posts in a case-insensitive manner.
