Final answer:
The question is about the use of non-equivalence operators and Boolean operators in search conditions. Boolean operators, like NOT, are used in searches to focus on necessary information and exclude the irrelevant. Examples include AND, OR, and NOT, each serving a distinct purpose in refining search results.
Step-by-step explanation:
The subject of the question pertains to the use of Boolean operators in database searches or programming, which are fundamental in forming logical conditions. While the specific use of the <>, !=, or ^= symbols as operators may vary depending on the context (such as database querying or programming), the question appears to be asking about operators that denote inequality. In the context of database searching, Boolean operators like NOT can be used to exclude certain results. For example, using "NOT" in a search would yield results that do not contain the undesired term.
Here's a brief rundown on how to use the basic Boolean operators:
- AND - Links necessary information by ensuring that the search results contain all of the specified terms.
- OR - Expands the search to include results that contain any of the specified terms.
- NOT - Excludes results that contain the specified term, narrowing the search field.
For example, a search string incorporating Boolean operators could look like this: "artificial intelligence" AND "Buiten" AND "2019". This will help in finding the exact journal source needed, using the specified title, author, and year.
