Now that I have your attention, this post is going to focus on thebasicBoolean search operators and search modifiers symbols and will not go into any detail of the many special Internet-only search commands/operators. Although a great many people seem to think that Boolean = Internet search, ...

A Boolean query pattern is composed of `AND', `OR', `NOT' operators and grouping with `(' `)'. Spacing between subpatterns is the same as `AND', `|' is the same as `OR' and a `-' is the same as `NOT'. The `OR' operator binds more tightly than `AND'. For example, --...
2: How to Use Boolean Data Type with Comparison Operators Comparison operatorsare commonly used in C programming to compare values and evaluate conditions. They return aBoolean data type, which is useful in decision-making structures and loops. For instance, if a condition is met, an action can...

However, when we consider multiple values, or items in the scope of other operators, it is useful to think in terms of translation. The idea of treating database enquiry as translation goes back to at least Bronneberg et al. (1980), and the use of inference for translation into database...
