The basics of Google search are the same, including how results are ranked and how Google determines relevant results. What has changed is the path you can take to get to relevant results.Here's what happens when you search:
Start to type. As you type a search on Google, the homepage automatically starts displaying your search results -- no need to press Enter. A list of predicted queries is generated using the autocomplete algorithm. These predictions are displayed in a drop-down menu below the search box.
See results. The algorithm tries to predict what the rest of your query might be based on popular queries typed by other users. The first prediction is shown in light grey in the search box, and the search results you see instantly will be for that predicted search. If instead you want to see results for only the text you've typed, just press Enter or click the Search button.
Type more, see more. If you continue to type, Google dynamically updates the search results to match the first prediction for what you've typed.
Refine your search. Don't find the information or website you want? It's easy to refine your search after seeing what results appear. Here are some options:
If you see what you're looking for in the list of predicted queries, click the query to see relevant results.
Use your keyboard's down arrow key to scroll through the list of predicted queries, and see results appear for each query you pause over.
Continue typing your query until the results show what you're looking for. As always, you're still able to type your full query and press Enter or click the Search button
