Dynamic Result Clustering Service /

Chapter 4
Dynamic result clustering narrows searches by providing dynamically formed subcategories that appear
at the top or right side of the search results.
The following illustration shows the dynamic result clustering at the top of the search results (enclosed
in the red box):
The search appliance generates alternative search queries by analyzing indexed documents based on a
user’s current search query. The results appear as query suggestions to help the user modify the query.
You can enable dynamic result clustering for a front end in the Admin Console at Search > Search
Features > Front Ends > Output Format > Search Results > Dynamic result clusters.
After enabling dynamic result clustering for a front end, the search appliance enables the XSLT
spreadsheet variables to enable the feature and specify the position on the search results page for the
dynamic result clustering:
1
position
Where position can be right or top.
When a user enters a query, the search appliance:
1. Uses the http://Search_Appliance/cluster.js JavaScript to provide the dynamic result
clustering.
2. Fetches the /cluster content.
