Description: &Default search algorithm for the process watcher. The filter is the logical AND of all attributes used to identify or otherwise narrow down resources. If the value of one of these attributes includes 'wildcards', then the watcher will basically behave like a one-to-many watcher, i.e. it may monitor two or more resources simultaneously. If set to 1 (positive-regular-expression), the agent searches for process resources that match the filter as a regular expression (case-insensitive). If set to 2 (negative-regular-expression), the agent searches for process resources that do not match the filter as a regular expression (case-insensitive). If set to 3 (positive-string-compare), the agent searches for process resources that match the filter as string comparison (case-insensitive). If set to 4 (negative-string-compare), the agent searches for process resources that do not match the filter as string comparison (case-insensitive).
