IWordBreaker interface (indexsrv.h)
Parses text and identifies individual words and phrases. This interface is a language-specific language resource component. It is used in background processes and must be optimized for both throughput and minimal use of resources.
Inheritance
The IWordBreaker interface inherits from the IUnknown interface. IWordBreaker also has these types of members:
Methods
The IWordBreaker interface has these methods.
| IWordBreaker::BreakText Parses text to identify words and phrases and provides the results to the IWordSink and IPhraseSink objects. |
| IWordBreaker::ComposePhrase Not supported. (IWordBreaker.ComposePhrase) |
| IWordBreaker::GetLicenseToUse Gets a pointer to the license information for this implementation of the IWordBreaker interface. |
| IWordBreaker::Init Initializes the IWordBreaker implementation and indicates the mode in which the component operates. |
Remarks
When to Implement
Implement this interface to create a custom word breaker for a language. Windows Search calls the methods of this interface when it builds content indexes and runs queries.Word breaker components for Windows Search run in the Local Security context. They should be written to manage buffers and the stack correctly. All string copies must have explicit checks to guard against buffer overruns. You should always verify the allocated size of the buffer and test the size of the data against the size of the buffer.
