Re: [Zope-dev] PathIndex doesn't index last part of path

A PathIndex is designed to make it more efficient to aggregate objects at various levels of containment. Their primary use case AFAIK is to allow to to limit queries to particular places within a hierarchy. The idea is to eliminate recursive searching of leaf level folders when you want all objects under a higher level and its child levels.

Also, by not indexing the nodes themselves, the index is an order of magnitude smaller and searches are therefore faster and it takes less room and is faster to update. This property need to be well documented.

At least, it is not intuitive. Dieter
