Pause will temporarily stop execution of your search and displays partial results. It is useful for temporarily reducing system resources on your computer so you can perform other tasks. It is also useful for performing large queries that my require you to run over the course of several ALS sessions and may extend over several days. When you pause, you are given the option to continue your query the next time you run ALS (multi-session queries). Taking this option will cause ALS to save some information in files so that the next time you run ALS, it will immediately continue executing your query. Not taking this option will allow you to only finish your query during your current ALS session. Multi-sesson query information is removed when a query completes normally, or when the multi-session option is used on a new query.
During a pause, you are not allowed to modify any of your search characteristics until your query is completed or until you abort your search. This is made clear by fact that all your various search controls are disabled while you are paused.
Pause is only available during certain times during execution of your search. It is currently available from the time that all query match URLs have been gathered (called unread results) until the start of the final merging phase.
Depending on when you pause, the partial results displayed in the Query Matches panel may include query matches in three states: Completed, Not Yet Analyzed, and Unread.
The results will be ordered from most complete to least complete and the order of the matches will follow the order returned by the search engines.
You can continue your query by pressing the Continue button.
Resumes execution of a search. The search begins execution from where it left off. Once execution resumes, you can once again pause the search.
Permanently stops execution of your search and displays partial results. The partial results show are like those described for Pause. Unlike Pause, Abort is available during all phases of the search process. Also, after an abort you are free to modify your search characteristics and enter a new query (Fetch).
