How to install
Unzip archive to Daz Studio's library folder. In my case it's D:/DSLibrary/Scripts/.
There should be 2 files:
Search On PoserContent.dse
Search On PoserContent.png
After this plugin will be available in Scripts folder in Content Library panel of Daz Studio. You can add plugin to menu "Scripts": right mouse click on plugin's icon and select "Create Custom Action".
