Notes de l'éditeur
- This might sound stupid but we’re increasingly dependent upon search facilities on websites.
- If the content your user wants is not immediately visible on your website then the power of your searching is critical to your applications success. Mapping applications are especially relevant here – content is embedded in maps.
- Yes – it may seem obvious but when presented with a map our users are searching for something on a map – a location for example.
- This is important and often neglected in many web GIS applications - there’s often an assumption that your users know something about your data and maps.
- If your search facility doesn’t do predictive it’s a big fail. Predictive searching stops your users making mistakes!Sorting your results in the next step - telling them what they might be looking for is cool, but getting it right is even cooler!
- Because maps usually have layers then grouping your search results can be useful.Remembering what I said earlier then sometimes your users don’t know what they’re looking for and they appreciate an aid
- Because maps usually have layers then grouping your search results can be useful.Remembering what I said earlier then sometimes your users don’t know what they’re looking for and they appreciate a middle step
- The basis of clustering in search is to provide intermediate steps into your resources – group and count, group and count, group and count
