WordPress search syntax

doesn’t support operation OR.

All keywords are AND‘ed.

A word “OR” in search query will be removed by default.
A word “AND” in search query will be kept by default. “AND” is treated literally.

Negation

Negation is supported by default. Place a minus (-) before your keyword (without space) to exclude this word.

Example

The search input “and vs or -english” will find articles containing the literal word “and” and “vs”, without “english”. Whether the articles contain the literal word “or” is unspecified.
