Class DutchAnalyzer

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public final class DutchAnalyzer
    extends ReusableAnalyzerBase
    Analyzer for Dutch language.

    Supports an external list of stopwords (words that will not be indexed at all), an external list of exclusions (word that will not be stemmed, but indexed) and an external list of word-stem pairs that overrule the algorithm (dictionary stemming). A default set of stopwords is used unless an alternative list is specified, but the exclusion list is empty by default.

    You must specify the required Version compatibility when creating DutchAnalyzer:

    • As of 3.6, DutchAnalyzer(Version, Set) and DutchAnalyzer(Version, Set, Set) also populate the default entries for the stem override dictionary
    • As of 3.1, Snowball stemming is done with SnowballFilter, LowerCaseFilter is used prior to StopFilter, and Snowball stopwords are used by default.
    • As of 2.9, StopFilter preserves position increments

    NOTE: This class uses the same Version dependent settings as StandardAnalyzer.
