title: Force my scrapy spider to stop crawling
body: <p>is there a chance to stop crawling when specific if condition is true (like scrap_item_id == predefine_value ). My problem is similar to <a href="https://stackoverflow.com/questions/3871613/scrapy-how-to-identify-already-scraped-urls">Scrapy - how to identify already scraped urls</a> but I want to 'force' my scrapy spider to stop crawling after discover the last scraped item. </p>
