After you have entered your main keyword, you can fine tune the results by using Must Also Mention and Does Not Mention filters.
With the Must Also Mention filter, simply add the keyword that must also be included in the results of your main keyword. If you add more than one filter, you can switch between matching "All" or "Any" of your filters.
Matching "All" is the most strict, and will show only results for your main keyword that also include ALL of the additional filter keywords.
Matching "Any" instructs Trackur to show only results for your main keyword that include ANY of the additional filter keywords.
Use Does Not Mention, to exclude any results that include any of your filter keywords.
