Fine-tuning your search to include or exclude specific job titles is straightforward:

1. Open the "Job Titles" tab within the search interface.

2. Locate the "Search by Job Title" section.

3. Here, you will find two input areas: "Include" for job titles you want to search for, and "Exclude" for those you want to omit.

4. Input the job titles you wish to include or exclude, placing one title per line in the respective section.

5. Press "Save and Search" to update your search results according to your specifications.

Your search will now reflect your preferences, including only the job titles you specified and excluding those you've listed in the "Exclude" section.
