With Clusterpoint you can make lightning fast custom search queries
with complex data ordering and grouping requirements, where search is
performed across a distributed cluster database in a very simple
querying format: as free-format Internet-style ad hoc search query
using any known content within a database. 
Outperform legacy SQL systems by a factor of 100 (with disk access) to
100,000 times (with RAM-only in-memory database), achieving sub-second
response times for your Web application. Please see more in section Search Simplicity.
Clusterpoint enables to store and manage all of your data in any
custom XML or JSON format, effectively search it Internet-style, even
with simple search keywords, and still get the most relevant data
upfront (on the first results page in web apps) at ultra-fast
sub-second speed - independently of the total database size and
without performance loss characteristic to SQL based systems when
databases grow big.
This ad hoc search is sometimes also refered to as full text search,
however, full text search is just a subset of ad hoc search. By ad hoc
search we mean that there is no need to program special search forms,
any know content can be used to query Clusterpoint database.
Clusterpoint Server built-in search engine handles all the search
across such a simplified and de-normalized structure database
without performance loss, characteristic to legacy SQL systems,
when database size grows big. Fast access and search to such a
database information is guaranteed through Information
Ranking, a scalable high-speed mechanism of our database
indexing facility that uses pre-sored ranked index and that works
in cluster storage architecture.
