When writing an essay, drafting a report, or reading a complex document in Microsoft Word, you frequently encounter terms, historical figures, or concepts you need to verify. The traditional workflow involves highlighting the text, copying it, opening a web browser, navigating to Google or Wikipedia, pasting the text, reading the result, and finally tabbing back to your Word document.
This constant context-switching ruins your focus. To solve this, Microsoft integrated the Bing search engine directly into Word via a feature called Smart Lookup. This tool allows you to perform deep web research without ever leaving your document.
What is Smart Lookup?
Smart Lookup is not merely a dictionary (although Word has one of those, too). It is an intelligent contextual search tool. When you select a word or phrase, Smart Lookup does not just search for that isolated term; it analyzes the surrounding text in your document to understand the context.
For example, if you highlight the word “Apple” in a document about fruit farming, Smart Lookup will return agricultural definitions and nutritional information. If you highlight “Apple” in a document discussing Silicon Valley and smartphones, it will return financial data, news, and history about the technology company.
How to Use Smart Lookup
Using the feature is incredibly fast and intuitive.
- Open your Microsoft Word document.
- Find a word, name, or short phrase you want to research.
- Highlight the text using your mouse.
- Right-click on the highlighted text.
- In the context menu that appears, scroll down and click Search “[Your Word]” (In older versions of Word, this button was explicitly labeled Smart Lookup).
A new panel will slide out on the right side of your screen. This is the Search pane, powered by Bing.
Navigating the Search Pane
The right-hand panel is divided into a few distinct sections designed for different types of research:
- Explore: This is the main results page. It typically displays a summarized Wikipedia entry at the top, followed by top web search results, news articles, and relevant images. You can read summaries directly in the pane.
- Definitions / Define: If you highlighted a single word, you will see a dictionary tab. Clicking this provides the official definition, pronunciation, and synonyms, similar to a traditional dictionary tool but often more comprehensive.
- Images: If you need a visual reference, the search pane provides image results. You can even click the + (Plus) icon on an image in the search pane to instantly insert it directly into your Word document.
Opening Links
If the short summary provided in the pane is not enough, you can click on any of the blue article titles. Word will immediately launch your default web browser and open that specific webpage so you can read the full article.
Privacy and Data Sharing
Because Smart Lookup relies on Microsoft’s Bing search engine, you must be connected to the internet to use it. Furthermore, because it uses contextual search, Word sends a small snippet of the text surrounding your highlighted word to Microsoft’s servers to improve the search accuracy.
The first time you use Smart Lookup, a privacy warning will pop up asking you to “Turn on” the feature, explicitly agreeing to allow Microsoft to process that snippet of text. If you are working on highly classified, confidential, or legally sensitive documents that absolutely cannot be transmitted over the internet, you should decline this prompt and avoid using the feature.
Availability
Smart Lookup is available in all modern versions of the software, including Word for Microsoft 365, Word 2021, Word 2019, and Word 2016. It is also available in the macOS version of Word and the free Word for the Web interface.
