com.yahoo.schema.processing.WordMatch

public class WordMatch
extends Processor

The implementation of word matching - with word matching the field is assumed to contain a single "word" - some contiguous sequence of word and number characters - but without changing the data at the indexing side (as with text matching) to enforce this. Word matching is thus almost like exact matching on the indexing side (no action taken), and like text matching on the query side. This may be suitable for attributes, where people both expect the data to be left as in the input document, and trivially written queries to work by default. However, this may easily lead to data which cannot be matched at all as the indexing and query side does not agree.

process

public void process(boolean validate,
 boolean documentsOnly)

Description copied from class: Processor

Processes the input search definition by modifying the input search and its documents, and returns the input search definition.

Specified by:

process in class Processor

Parameters:

validate - true to throw exceptions on validation errors, false to make the best possible effort at completing processing without throwing an exception. If we are not validating, emitting warnings have no effect and can (but must not) be skipped.

documentsOnly - true to skip processing (including validation, regardless of the validate setting) of aspects not relating to document definitions (e.g rank profiles)
