On the Web Services topic click 
Refresh.
The Web Services Map Parts allow you to search various online sources for information or items. The search results are returned as subtopics of the map part topic. Each result contains an item summary (as a topic note) and a link to the item.
If you attach a Web Services part to an existing topic, the topic's text is automatically used as the search term. You can change this when you are prompted for the search parameters..
Open the Map Parts pane by doing one of the following:
Click the Map Parts Task Pane tab.
On the Ribbon Insert tab or Tools tab, click Map Parts.
In the Map Parts pane, click the Web Services folder.
(optional) On the map, select or create a topic with your search term.
In the Map Parts pane, click the part to add it to the selected topic, or drag it to a topic on your map.
You will be prompted for search parameters.
After a short pause, the Web Services part appears, populated with the search results.
You can point to the Notes icon to see a description of each found item, or click its link to go to its web page.
You can update the search parameters for a Web Services topic that you've already added to the map. The new search results will replace the current results.
On the Web Services topic right-click its icon.
Click the search name (for example "Amazon Search") and enter the new parameters in the dialog.
Click OK.
The Web Services topic updates automatically with the new results.
To change only the "Look for" term, just change the Web Services topic's text. The search results update automatically.
If some time has elapsed since your initial search you can update the Web Services topic to see the latest available results:
On the Web Services topic click
Refresh.
You can add your own subtopics to the Web Services topic or to the search results, and you can also edit the results topics to include your own text. Your additions will be retained when the Web Services topic is refreshed, unless the result topic you modified is removed on refresh.
