Job seekers can use occupation titles to identify their current or most recent job title held as well as what they want in the jobs to be searched. To make searching easier, Occupation titles are organized in the form of a multi-level tree. 

1) When selecting the current occupation title in the resume input form, job seekers should take care to choose a title that is as low in the tree as possible. Lower levels mean more specific titles. 

2) Higher levels are broader in scope. Here the title refers to the entire collection of titles in the branches below it. While identifying occupation titles as prefrences for searching jobs, the job seeker should select the high level titles. By choosing an appropriate high-level title in the tree, the seeker will find all jobs that match that title as well as any of the titles in the lower levels.

Limitations of "Occupation Titles": As Job Titles become less meaningful and vague, it is becoming increasingly difficult for Job seekers to find jobs or Employers to find candidates solely on the basis of matching occupation titles.

Job titles can only convey the expertise or functions accurately if they represent "stereotype" roles or well known titles such as Electrician, Carpenter Film Director, Pilot etc. For this reason, the JOBSAtAnytime+ program ALSO uses "Functional Areas" and "key skills" for mapping expertise and conducting searches.

You could use key skills in conjunction with occupation titles or even drop occupation titles where they are not meaningful. Read an article about occupation titles.
