Dynamic Result Clustering Service /
cluster Protocol 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:
<!-- *** dynamic result cluster options *** -->
<xsl:variable name="show_res_clusters">1</xsl:variable>
<xsl:variable name="res_cluster_position">position</xsl:variable>
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.
