Use the following procedure to enable automatic query guidance.
Open the IDOL Server configuration file in a text editor.
In the [Server]
section, configure the following parameters:
QuerySummaryAdvanced
|
Set this parameter to True to enable the advanced algorithm that IDOL Server requires to provide query guidance. This algorithm clusters the best terms and phrases in the query results, and uses the phrases of the top clusters as query summaries. The default value is False . |
QuerySummaryLength
|
Set this parameter to the number of cluster phrases to generate. To provide good query guidance phrases, enter a number that is large enough to allow IDOL Server to generate high-quality clusters. However, setting QuerySummaryLength too high might slow the query performance (a sensible maximum value might be 25–100). The default value is 10 . |
QuerySummaryTerms
|
Set this parameter to the number of terms that the algorithm for QuerySummaryLength can use to generate the query summaries (a sensible value might be 50–500). The default value is 0. In this case, IDOL Server uses the specified TermsPerDoc number, which in turn defaults to 50. |
Tip: You can also set these parameters in the Query
action so that you can test different values without reconfiguring IDOL Server, or tune QuerySummary
functionality for different uses.
