Search for parentage throughout the hierarchy

[srdiamond]

Regarding limited searches based on multiple infoitems, I think this would amplify the power of logical linking, because linkages would become a lever for searches. It gives the user a _reason_ to use multiple links, even if doing so isn't otherwise necessary. Multiple linkages become an easy way to cross-reference the info-items with very powerful keywords, the ancestor topics in the structure.
