The old mantra is "yes, if you have money and time".
The Thanks is a modification and does not fall under the forum software as it is purchased. For that the 'thanks' fields were never included in the search mechanism.
It will require extensive modifications to display what you are asking and like I wrote before it is very taxing for the database.
In your case: You have 425 posts.
The system then will have to join each of those posts with all the users and scan through those to see who has thanked you for that post.
Multiply 425 with 125000 users and you get how many scans the script has to perform after it has filtered through your posts.
It is not the time filter that helps (30 days). The query has to be redesigned and more data has to be introduced to ensure that you get what you want without 'killing' the database.
The old thank you button had a different structure which made that information easier to be accessed while introduced slowness in the normal operation of the forum since each post required twice as many queries to be generated, thus slowing the forum down.
Once I finish the scheduled optimizations I will revisit this one and see what I can do.
