When you enter your search queries, try various combinations of keywords, but stay broad if possible in order not to miss potential opportunities.
While it is important to browse the Web for job openings, most jobs are found by way of networking, so do not underestimate the importance of getting out there and reaching out to others. It may be difficult at first, but if you're committed to finding work, you cannot dismiss this route.
As you proceed in your job search, it is important to stay organized and keep records of what positions you've applied to, as well as a copy of the job applications you sent out. While it is important to have a good appreciation of all the job openings available, when comes the time to choose where to apply, it may be preferable to apply to less positions but spend more time tailoring your applications. Avoid sending generic resumes and cover letters at all costs.
