org.dbpedia.spotlight.lucene.LuceneManager
This class defines a policy for storing/searching in lucene. It defines the correct behavior if you want to search for a Surface Form, DBpedia Resource or Context. Whenever possible you should use the methods here instead of implementing your own lucene-specific code. Since the Analyzer and Similarity classes have to be the same for indexing and searching, they are kept here. The case insensitivity behavior also should be used consistently across classes, so we keep it here as well. TODO Should be singleton to assure that reader and writer are using the same config? TODO there should be a generic AnalyzedSurfaceforms that takes a SpotlightConfiguration object, pulls the analyzer and uses it. see the redundancy between N-Gram and Phonetic. The CaseInsensitive could be done the same way. @author pablomendes
