showing in search results

Issue Summary

Hi, great module -- finally signatures the way they should be presented! :)

I noticed that the signature is being displayed as part of the search results, even though the nodes in which it is being shown are not actually nodes that I am displaying signatures in, if that makes any sense.

For example, an amazon node being listed in the search results also shows part of my signature, which it shouldn't, because when you click on that particular node to view it, the signature isn't there (which is correct). Any ideas?

Thanks,
Brad
