When to Use \"OR\" in Your Search Queries
When you are using a search engine to find information on a specific topic, you might use multiple keywords to help you get the best results. In some cases, using the word \"OR\" can help you expand your search by indicating that you are looking for pages that contain either one keyword or another. Heres when and how to use \"OR\" in your search queries.
When to Use \"OR\"
You should use \"OR\" when you want to broaden your search results by searching for pages that contain either one keyword or another. This is especially helpful when you are unsure of exactly what terms others might use to describe a specific topic, or when you are exploring a broad topic for the first time.
For example, lets say you are trying to learn more about different types of exercises. You could search for \"types of exercises,\" but you might get pages that only focus on one type of exercise, like yoga or weightlifting. To broaden your search, you could use \"OR\" to search for \"types of exercises OR workouts.\" This way, youll get pages that contain information on both exercises and workouts.
How to Use \"OR\"
To use \"OR\" in your search queries, simply type the keyword \"OR\" in uppercase letters between the keywords you want to search for. Heres an example:
Types of exercises OR workouts
Make sure to keep a space before and after the keyword \"OR\" so that the search engine can properly interpret your query. You can also use parentheses to group keywords together, which can help create more complex search queries.
When Not to Use \"OR\"
\"OR\" can be a powerful tool in your search queries, but its not always the best choice. If you want to narrow down your search results to a specific topic, using \"OR\" might actually make your search less useful. In that case, its better to use more specific keywords.
For example, lets say you are trying to find information about different types of exercises that are good for people with back pain. You could search for \"types of exercises for back pain,\" but adding \"OR\" to your query might not give you the most relevant results. Instead, its better to use more specific keywords like \"back pain exercises\" or \"exercises for lower back pain.\"
