A search query consists of one or more search terms, along with zero or more parameters, such as Boolean operators, and wildcards.
An automatic AND is assumed between words entered next to each other in a search query. For example, a search for bird cat dog returns the same search results as bird AND cat AND dog.
Query terms are not case sensitive, and punctuation marks, such as hyphens, commas, and semicolons, are ignored.
Query length of up to 64,000 characters can be accommodated in both Advanced Search and the main keyword search.
The search results query text rendered immediately above Search Results shows you how searches have been parsed.
