I am trying to learn how to create plugins that search websites containing conference proceedings, such as https://asmedigitalcollection.asme.org/IDETC-CIE. To do that, I tried to go through the example in the Help documentation to create a plugin for the ACS. I could not follow the instructions to the letter because for some reason, when I created the new ACS plugin, the Test option is greyed out, so I cannot go through and exclude any domains. However, I tried to just write the plug-in as specified in the help, but I get no results. Then I tried using the built-in plug-in for the American Chemical Society (under Science), but I could not get that to work either. When I select that plug-in and search for Mercury, I get no results. Now I am just very confused.
Here are some screenshots to show how I am trying to use the built-in ACS plug-in:
Once I figure that out, if you have any advice or examples that would help me create a plug-in for a site such as https://asmedigitalcollection.asme.org/IDETC-CIE, I would appreciate it. I have tried many many iterations of trying to follow the instructions in the help manual and cannot get good results (i.e., I cannot get results that include what I find when I search the same term on the website).
Thanks in advance.
