What is the result of the query expression (grape OR apple) (banana OR pear) in dtSearch?

In dtSearch, the query expression (grape OR apple) (banana OR pear) is designed to combine multiple terms with logical operators. The use of parentheses in this case signifies that the terms within each set should be considered together in their respective groups.

The correct interpretation is that the query combines the two groupings through an implied AND operation. Thus, the query aims to return documents containing at least one term from the first grouping (grape or apple) and at least one term from the second grouping (banana or pear).

The choice that correctly indicates the behavior of dtSearch with the given query is that it returns documents with the terms 'grape', 'apple', 'banana', and 'pear'. This reflects the intended logical operation of selecting documents that feature terms from both specified groups while adhering to the query's structure.

The syntax is valid, and the parentheses serve to clarify the precedence of the logical operators involved, ensuring that dtSearch processes the query as intended rather than ignoring the grouping of terms. Thus, the correct visibility and function of the terms within their logical context are maintained.
