You can use Boolean operators in your search to customize search results by combining keywords. Here's how you can do it step by step:

1. AND Operator: If you want to search for documents that must contain two keywords, you can use the AND operator. For example, if you are looking for articles that contain both "climate change" and "global warming", you can search "climate change AND global warming".

2. OR Operator: If you want to search for documents that contain either of the keywords, you can use the OR operator. For example, if you are looking for articles that contain either "climate change" or "global warming", you can search "climate change OR global warming".

3. NOT Operator: If you want to exclude a certain keyword from your search, you can use the NOT operator. For example, if you want to find articles about "climate change" but not about "global warming", you can search "climate change NOT global warming".

4. Combining Operators: You can also combine these operators to make your search more specific. For example, if you want to find articles about "climate change" and either "global warming" or "ozone depletion", you can search "climate change AND (global warming OR ozone depletion)".

Remember to use parentheses to group keywords together when combining operators. This will ensure that the search engine understands exactly what you're looking for.
