Quotation marks: You may include quotation marks to limit your search to an exact phrase match.
The + operator makes the word it’s attached to mandatory. For example, searching for advisory committee will include all posts that have one of these words. Searching for advisory +committee requires all posts returned to include the word “committee”, and they may also include “advisory”.
The - operator excludes a word from the results. Searching for advisory -committee returns all posts that have the word “advisory”, but not the word “committee”.
