1. A processor-implemented method of collaborative focused crawling of documents related to focus topics on a network, the method comprising: selectively prioritizing the documents to crawl based on a set of rules; fetching prioritized documents from the network; for each fetched document, determining whether the fetched document is relevant to any of the focus topics; crawling the fetched document that matches any of the focus topics such that the fetched document is crawled only once even if the fetched document matches a plurality of the focus topics, wherein the fetched document comprises a document of interest for access by a user; further crawling out-links on the fetched document based on an assumption that if the fetched document is of interest, the out-links are also of interest; determining whether the fetched document should be disallowed, and upon determination that the fetched document should be disallowed: selectively disallowing the fetched document; identifying a resource locator string associated with the disallowed fetched document; placing the resource locator string for the disallowed fetched document in a blacklist in order to prevent future crawling of the fetched document; wherein the crawling is performed using a collaborative focus by analyzing the documents for more than one focus topic of the focus topics at a time by implementing a foreman function for reading a plurality of contents of the resulting uniform resource locator strings, and sequentially passing the contents of the resulting uniform resource locator strings to a plurality of sequentially configured miners that each represent an individual focus topic, wherein each miner is configured to insruct a fetcher to crawl a plurality of out-links on a document of the resulting resource locator string whenever the contents of the resulting resource locator string match the specific focus topic of the miner, and wherein each miner is configured to ignore the resulting resource locator string whenever the contents of the resulting resource locator string do not match the specific focus of the miner; and analyzing a plurality of fetched documents obtained from the crawling by providing a graphical indicia of one or more properties that are indicative of which of the plurality of fetched documents represent a best source of information for a specific topic within the plurality of fetched documents.
