FILE NAME INTERPRETATION IN "FIND" TOOL

I am using BRIDGE 14.1.4.307 version. In the tool "EDIT/FIND/Filename/ends with" system interprets file extension as part of the name of file, so if you want to find what "jpg" files have a name ending with the word "house" you have to write "house.jpg". I think that the file extension should not be considered as part of the file name. Thanks.
