Configure the IDOL Content component to Enable Dynamic Clusters
Use the following procedure to enable dynamic clustering in the IDOL Content component.
-
Open the IDOL Content component configuration file in a text editor.
-
In the
[Server]
section, set the following parameters:QuerySummaryAdvanced Set this parameter to
True
to enable the advanced algorithm that provides dynamic clustering. This algorithm clusters the best terms and phrases from the query results, and lists them.The default value is
False
.QuerySummaryLength Set this parameter to the number of cluster phrases to generate. Setting QuerySummaryLength too high can slow the query performance (a sensible value might be 25–250).
The default value is
10
.QuerySummaryIDs Set this parameter to
True
to return the document IDs of the parent documents that phrases come from. The IDs return in the list that Content generates when you perform an action with the QuerySummary parameter. You can use the IDs to display the number of documents that each dynamic cluster contains.The default value is
False
.QuerySummaryTerms Specify the number of terms that the algorithm for QuerySummaryLength can use to generate the query summaries (a sensible value might be 50–500). If you set this parameter to
0
, Content uses the specifiedTermsPerDoc
number, which in turn defaults to50
.The default value is
0
.TIP: You can also set these parameters in the Query action so that you can test different values without reconfiguring Content, or tune QuerySummary functionality for different uses.
