Fix script that pulls content from Yahoo Answers and Amazon Askville [de

I have a forum posting script that pulls content from 3 sources.....Youtube, Amazon askville, and Yahoo Answers. The script uses a bot to scrape content from those 3 sources after entering your chosen keywords. The script seems to scrape content that has nothing to do with the keywords or categories it's supposed to get results for. I need a highly qualified person (preferably someone who has worked with bots like these) to fix this script so all the results come back on topic and accurate. I need someone to remake this bot so it's hyper accurate almost with an advanced search quality. It needs to follow some kind of rules so the content is on topic per my chosen keywords. I don't care how you do it or how much of the script you have to modify....I need this working properly asap. Please do not bid unless you have experience with what I listed above. I hired a programmer from here to do this job and he was unable to get this working as expected.
