// this class is used to search off-line news databases, usually for
|
|
// applying off-line retrieval options to a database, or for applying
|
|
// header/article retention policies. We are using search to get its
|
|
// background url handling for free, and its matching engine.
|
|
|
|
// We had to subclass MSG_SearchPane to override GetURL (so we can provide
|
|
// our own exit function so that we can go on to the next part of the process)
|
|
// We subclass the Starting and Ending Update functions so we can look at
|
|
// each result as it comes in.
|
|
|
|
// Searches for retrieving off-line will typically look like this:
|
|
// Date > 01/23/96 AND Date < 01/23/97 AND Size < 5000 AND Status != isRead
|
|
// AND Status != Offline
|
|
|
|
// Searches for purging articles will typically look like this:
|
|
// Date < 01/23/96 AND Status == isRead AND Status == Offline
|
|
|
|
// Searches for purging headers will typically look like this:
|
|
// Date < 01/23/96 AND Status == isRead
|
|
|
|
// Customers will either wait for the whole array of matching keys
|
|
// to be constructed before acting on them (e.g., Offline retrieval)
|
|
// or will act on each key in turn (purging articles or headers). We
|
|
// could require that customers who want notification of each add
|
|
// become view listeners. Oh sure, why not.
