Auditing Advanced Search

walpoletim

Using WDK, I have extended Search60 - onShowResults to audit a search, and have managed to audit the basic search by calling the function

this.getSearchInfo().getQueryDescription()

However - I need to be able to record all the search details from an advanced search, and am looking for a way to do this.

One possibility would be to store the DQL that was run.

Is there any way to obtain the DQL of an advanced search, or does anyone else have any recomendations?

Thanks

Hi Tim,

In your class that extends Search60, you should register you own queryListener (i.e. a class that implements IDfQueryListener). An IDfQueryListener implementation must implement three methods onQueryCompleted, onStatusChange, and onResultChange. WDK supports asynchronous results processing. For the purpose of auditing, onQueryCompleted is the method that should contain your auditing code because it indicates that the search is complete. onResultChange is called each time a new batch of results is returned and onStatusChange is called when the status of a search source changes.

It happens that I have an example handy because we do a lab in the Architecting EMC Documentum Applications training course in which we audit WDK searches. I am attaching an implementation of a Search60 customization that audits both one box and Advanced search. In this implementation, the following is logged to the audit trail 1) the full text search terms, 2) the name of the user that issued the search, and 3) the response time. You can audit other characteristics of the search by interrogating the IDfQueryBuilder interface accessible via WDK's SearchInfo object. I don't think you can get a DQL string rather you can get things like the object type, search operators, and so forth. Here's an example of how to get the full text search terms using IDfQueryBuilder:

/*
  * Obtain the full text search terms from the IDfQueryBuilder interface
  *
  * @return String containing search terms
  */
private String getSearchWords() {
  String searchWords = null;
  SearchInfo info = getSearchInfo();
  IDfQueryBuilder qb = info.getQueryBuilder();
  IDfExpressionSet expressionSet = qb.getRootExpressionSet();
  IDfEnumeration exprEnum = expressionSet.getExpressions();
  while (exprEnum.hasMoreElements()) {
   IDfExpression expr = (IDfExpression) exprEnum.nextElement();
   int exprType = expr.getExpressionType();
   switch (exprType) {
   case IDfExpression.EXPR_TYPE_FULLTEXT:
    IDfFullTextExpression fullTextExpr = (IDfFullTextExpression) expr;
    searchWords = fullTextExpr.getValue();
    break;
   }
  }
  return searchWords;
}

Good Luck!
