Description

PISCO configures their metacat server to index only absolute paths in their metadata documents (rather than relative paths), which decreases the size of their index tables by about 3/4 and results in significant query speed improvements.

This requires also refactoring clients (skins, Morpho, Kepler, ...) to only pose queries with absolute paths, as the queries would otherwise not take advantage of the index.

Investigate whether there are advantages to this approach for the KNB metacat installations -- I suspect it would, as the xml_index table would decrease in size massively. This may be important as we work on building the size of our collection through DataONE.

Also will look at having the ability to keep relative searches by searching on absolute paths.
