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.- Author:
