Configure the IDOL Content component to Generate Query Summaries
Use the following procedure to enable query summary generation.
-
Open the IDOL Content component configuration file in a text editor.
-
In the
[Server]
section, set the following parameters:QuerySummaryLength
Set this parameter to the number of query summaries to return when you perform an action that includes the
QuerySummary
parameter.For example, if you set
QuerySummaryLength
to5
, Content identifies the five top phrases or terms that the result documents contain, and returns them in a comma-separated list. If Content cannot find your requested number of relevant phrases or terms, it returns fewer.The default value is
10
QuerySummaryAdvanced
Set this parameter to
True
to use an advanced algorithm to generate the specifiedQuerySummaryLength
number of query summaries. This algorithm clusters the results and uses the phrases of the top clusters as query summaries. This process produces better query summaries, but is more system intensive.Set this parameter to
False
if you want query summaries without first clustering the results.The default value is
False
.QuerySummaryTerms
If you set
QuerySummaryAdvanced
toTrue
,QuerySummaryTerms
allows you to specify the number of terms that the algorithm uses to generate the query summaries (a sensible value might be 50–500). If you setQuerySummaryTerms
to0
, Content uses the specified value ofTermsPerDoc
, which in turn defaults to 50.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 the IDOL Content component, or tuneQuerySummary
functionality for different uses.
