To make sure that both of the terms you are searching for appear in the document, use a '+' symbol. If you want the terms to appear in the exact order as a phrase or term, use quotation marks.

When two search terms are connected with the AND Boolean operator, the number of results (hits) will generally decrease. This is because the AND operator requires that both terms must be present in the search results, which narrows the focus and limits the pool of relevant documents. Consequently, the results will be more specific, targeting only those sources that include both terms.
It would depend on the system, but probably "AND". For example, a query '"used" AND "cars"' should return only documents containing both terms. Sometimes the AND operator is represented symbolically, such as "used" && "cars". Again, it depends on the context.

The boolean operator that omits information from the search parameters is the NOT operator. When used in a search query, it excludes specific terms, helping to refine results by filtering out unwanted content. For example, searching for "cats NOT dogs" will return results related to cats while excluding any mentions of dogs.
The answer will increase in numbers.
The answer will increase in numbers.
When two search terms are connected with the "OR" boolean operator, the number of search results will typically increase. This is because "OR" broadens the search to include results that contain either term or both terms. As a result, using "OR" tends to retrieve a larger set of relevant documents compared to using "AND," which narrows the search.
