Comment 6 for bug 137621

I investigated this recently. I tried to fix this when I added the reciprocal links between packages and projects because once I saw a search fail, I wanted to play the search against the alternate target. This relates to several bugs that I cannot find after the merger of Lp projects.

1. search criteria needs to be preserveable for links. This mean a helper function that makes search links need to know about ever search option (we can even make this function remove usless params).
2. The package-project link needs updating and/or...
3. Add search again, Search in <location> links,
