Hits From a Substructure Search

Q:

When searching using a substructure I obtain numerous hits that do not relate to the compound for which I am searching. Why?

A:

If you have entered a structure that contains only the carbon atom framework without the correct bond orders the program will not recognize the fragment as a substructure contained in your particular substance. Please ensure that all bond orders within the fragment are correct. If the problem persists please contact us for assistance.
