Search Query Types
Search queries can be done in a variety of ways.
AND Searches
To get results that match multiple words, simply type the words that you want to find. This is the default behavior of search.
OR Searches
To search for data that may contain one of a few terms, but not necessarily all of the terms, enter the keyword OR between each search term: "dogs OR cats" or "dogs OR cats OR birds".
Note: The keyword "OR" must be capitalized. The search module will treat the lowercase "or" as another word to find. Because "or" is smaller than the default search word length (3 characters), the search module will ignore "or" to create an "AND" search instead.
Exclusionary Searches
You can even filter for things that don't exist. For example, if you want to find pet stores that do not have chickens, you need an exclusionary search. You can do this using the minus "-" sign. For example "pet stores -chickens" finds all pages with "pet" and "stores that do not also contain the words "chickens".
