Hello, everyone!
I am now trying to find a structure in literature, in which two units are linked together, regardless of what the link is. however, I could not be
able to draw that structure in Discovery gate or Beilstain crossfire, that is, you cannot just simply put two units in that search window. Does any
one know how to solve it? Thank you so much for your regards!

Your description is rather unclear. Do you mean to say that you want your two units to be connected by a variable-length chain? I believe there should
be such a tool for drawing that in there.
Otherwise, just do a substructure search for each of the two units.

P.S. Shouldn't this be in "References" or "Miscellaneous"?
