I have made a custom search for houses.
The problem is that I have to show in the search results page, a "googlemaps" with the points at which there is a house, according to the search results obtained.
How can I do it?
@Richard, it's hard to answer this in detail with this little details. Do you need to pinpoint a single house? Will you use an address or will you use latitude and longitude?
My suggestion would be to take a look at this excellent Google Maps Plugin for jQuery. jQuery is part of any WordPress installation, so you wouldn't need to install anything else. Additionally this is quite easy to load.
Below a quick example of how I've implemented this, using custom fields to store both a latitude and a longitude. But you could just as well get an address returned as a search result and add that:
