If you are looking to collect data that matches your categories or keywords of interest, and you wish to be alerted the moment it got published somewhere in your list of interested sources, then low-latency crawls
can be your data partner.
This process involves creating an internal index of all the relevant data after crawling them, and then searches through the index for pre-defined list of keywords. Query results are presented in a structured format. Files contain document-level details of the article or blog or news that was crawled.
