A section of my website needs to search updated content from among 50 websites and output results.

Now what I earlier had was parsing these RSS feeds every hour using a cron job(every hour) and storing them in my database and then executing the search function.

However, I am on a shared hosting and my host warned me against consuming too much bandwidth which this function is supposedly consuming. So, I am looking for an alternative way which can lessen the burden on bandwidth.

So, I was thinking if the RSS parsing can be done with the help of an API. I could not confirm if there is an official Google Reader API that can perform this.

Even if this is available, how do you suggest I perform the search function. Should I necessarily store it on my own database and perform the search function or is there an other way possible.

Thanks for your ideas.
