The ID is assigned when you specify to the Refresh Scheduler the total number of crawlers you are running, and when you update the variable '$num_crawlers' from inside of review.php and graveyard.php (line 73) to the number of crawlers you are using. The scheduler will assign pages in round-robin order a crawler ID within the range of that total.\n\nExample: If you want two crawlers running, then you should specify the first with an ID of 1, and the second with and ID of 2. Run them in separate folders, and provide a symlink to the 'robots' folder and 'shards' file in each. Each crawler will crawl pages in the indexqueue with its corresponding ID.\n\nYou can also not assign an ID, and in that case the crawler will ignore the ID assignments. So if you have only one crawler running, assigning an ID is optional unless you need to change the sleep time (then just use an ID of 1). Don't run multiple crawlers without assigning ID's.\n\nSpecify the total number of shard tables you wish to use in the 'shards' file. The crawler will round-robin insert/update rows in these tables (ws0 to wsX) along with the main 'windex' table. The default is 4.\n\nThe Sleep_Time is 1 second by default but can be set to 0 or higher, and is used when crawling hyperlinks is specified. It inserts a delay between each link that it crawls. This delay is not used between individual pages that were submitted by people.\n\n");
