An alert search mechanism is used with search engines such as a crawler to search for desired documents and/or resources. Particular documents are found by using search queries. The search mechanism track values of a set of relevant properties in queries. Whenever a document is searched for by the system, the values of these set of properties are matched with the old value. If there is no match, this is an indication that the document has changed.

Methods and computer-readable media are provided for performing a search on a relational database. According to one method, a query class is provided that includes properties that specify how a query is to be performed and how results from the query are to be returned, and an execute method that is called to perform the actual query. A keyword query class derived from the query class is also provided that includes keyword query properties and an execute method for performing the keyword query. In order to perform a keyword query of an SQL database, an instance of the keyword query class is created, the properties set on the instance, and the execute method called. When the execute method is called, the specified properties are translated into an equivalent SQL statement and the search is performed on the identified relational database by a search service.
