Creating distribution lists, filter contacts

I have a local folder with 300 contacts from different companies och with different job titles. I manage to create a distribution list but how can I filter the contacts to create a list with, for example, ONLY job-title Chairman.
What is the syntax for the filter function.
Most grateful for all help / Stellan Dahlberg

If you go to the Contacts section of eM Client and click the down-arrow in the Search box. Click on Advanced Search.

Not sure which field you use for job title, but you can add it in the search.
So if it is Profession, select that and add Chairman to the field, then click Search.

This will show all Chairmen in the results.

Select all the contacts displayed, and by right-click choose Create Distribution List. All the search results contact will be added to the new DL.
