Class DefaultAnalyzerFactory

java.lang.Object

com.bigdata.search.DefaultAnalyzerFactory

All Implemented Interfaces:

IAnalyzerFactory

Deprecated.

Using ConfigurableAnalyzerFactory with the ConfigurableAnalyzerFactory.Options.NATURAL_LANGUAGE_SUPPORT uses the appropriate natural language analyzers for the two letter codes and for tags which include sub-tags.

public class DefaultAnalyzerFactory
extends Object
implements IAnalyzerFactory

This is the default implementation but should be regarded as legacy since it fails to use the correct Analyzer for almost all languages (other than English). It uses the correct natural language analyzer only for literals tagged with certain three letter ISO 639 codes: "por", "deu", "ger", "zho", "chi", "jpn", "kor", "ces", "cze", "dut", "nld", "gre", "ell", "fra", "fre", "rus" and "tha". All other tags are treated as English. These codes do not work if they are used with subtagse.g. "ger-AT" is treated as English. No two letter code, other than "en" works correctly: note that the W3C and IETF recommend the use of the two letter forms instead of the three letter forms.
