@enkirkby:

Are you saying that you have a Custom Column with a user-friendly name of "Original_name" that has a "Search/Lookup Name" of "#original_title"? Why isn't the name "Original Title"? Or is the name really "#original_name"?

Please post a screen snip of your Calibre > Preferences > Add Your Own Columns > Edit Settings for your "#original_title" column. I need to see what kind of Custom Column it is (TEXT or COMMENT). It must be identical to the type that "title" is, TEXT. If not, and it is a COMMENT type, it may have HTML tags in it, and will never be identical to pure text. In that case, you need to create a new TEXT version, and use that instead.

In the meantime, test using an Operator of "contains" instead of "=". That might work if the value is contiguous (not separated by any HTML tags).

[EDIT:] But "SWAP" the right side of your parameters "vertically" so the question is: "Is title contained in #original_title", not the reverse.
