SUNSPOT

Sunspot is a library providing a powerful, all-ruby API for the Solr
search engine. Sunspot manages the configuration of persistent Ruby
classes for search and indexing and exposes Solr's most powerful
features through a collection of DSLs. Complex search operations can
be performed without hand-writing any boolean queries or building Solr
parameters by hand.

WHAT'S NEW IN SUNSPOT 1.0

Sunspot 1.0 supports Solr 1.4, including new features like multiselect
faceting and Trie range queries. Sunspot 1.0 also introduces "assumed
inconsistency", in which Sunspot gracefully handles frictional
inconsistency between Solr and the primary data store.
