Correctly cache doc title in the spatial cache

fix to docid overrides to handle an empty result set

Fixed geometry logic to swap north and south if n < s

Reverting to previous QueryTerm.java that uses 'LIKE' for comparisons. This
allows substring matching to work properly, but prevents the postgres index
from being used. As a result, full table scans are done on the tables, causing
a major performance hit. Need to determine how to eliminate the use of LIKE...

Modifications to the table definitions to add indices that should be used
when searching the database. Added an upgrade script to create these
indices as well. Modified QueryTerm.java to use the '=' comparator rather
than 'LIKE' so that we can do index scans rather than table scans. This needs...

fixed point centroid calculation to reflect bboxs that cross the dateline

fixed point centroid calculation to reflect bboxs that cross the dateline

Make spatial query more accurate by actually intersecting geometries in addition to a simple bbox filter. Important for testing intersection of irregular shaped objects or multi-geometries

Added docid override mechanism to DBQuery. Bypasses the queryspec.printSQL method and creates an optimized docid query in cases (like the spatial query) where you know the docids a priori

Updated spatial query to also look at point spatial cache as some documents may only be represented as a single point.
