Collections and the ColdFusion MX Verity architecture
ColdFusion MX includes Verity K2 Server search technology. Verity K2 Server is a high-
performance search engine designed to process searches quickly in a high-performance,
distributed system. The K2 search system has a client/server model. K2 client applications, such
as ColdFusion server, provide users access to document indexes stored in Verity collections. K2
Server supports simultaneous indexing of distributed enterprise repositories, and handles
hundreds of concurrent queries and users.
The Verity search system takes advantage of the latest advances in hardware and software
technology, and provides the following features:
•
Multithreaded architecture
•
Support for Verity knowledge retrieval features, including topics
•
Continuous operation support
•
High scalability
•
Category support (also called parametric indexes)
Note: ColdFusion MX no longer uses VDK mode and K2 mode. All Verity processing now uses the
K2 architecture. Additionally, ColdFusion MX no longer uses the neo-verity.xml file.
Because ColdFusion MX reads custom queries into memory, indexing a large query result set can
cause a "Java out of memory" error or lead to excessive disk use on your computer if your
ColdFusion MX Java Virtual Machine (JVM) memory allocation is too small. Manage
ColdFusion JVM memory settings as follows:
