Editing Final Report 2011 (section)

===Technical Challenges===
System Integration introduced the following challenges:
# Multithreading thread control
# Pattern Matching generics
# Intuitive GUI design
# Internet access proxies

The access of the crawler through a GUI meant the GUI Java thread needed control of the web crawling threads, providing some multithreading challenges. Generic object use between the different pattern matching algorithms also introduced a challenge. This was solved as noted in the [[Final Report 2011#Pattern Matcher| Pattern Matcher]] section with the introduction of the ''SearchManager'' Java interface.

Other challenges came from the designing of a GUI providing all necessary input areas for a user to run a web search and from internet proxy issues which were encountered accessing the web from some locations.
