The Google Ajax Search API is designed to work seamlessly with the Google Maps API. One way it adds instant value is to allow your Maps-based applications to execute a search, then take the search results and plot them on a map. Our model for this is simple and straightforward — each search result is a JavaScript object that contains a number of properties including a URL, title, array of phone numbers, street address, city, latitude and longitude, etc. Therefore, adding a search result to a map is as simple as:
var latLng =  GLatLng(parseFloat(result.lat), parseFloat(result.lng));
var marker = new GMarker(latLng);
myMap.addOverlay(marker);
The AJAX Search API team produced a number of simple sample applications to teach the basics of search-integrated Maps mashups. Two of the most popular samples are My Favorite Places and My Phone List, so take a look and see if they inspire you to add Search to your Maps mashups!

(An example of this search-enhanced Maps mashup idea is the Google Gadget we built using these two APIs — check out the new Google Map Search Gadget.)
