Class ConfluenceFilenameAnalyzer

  extended by org.apache.lucene.analysis.Analyzer
      extended by

public class ConfluenceFilenameAnalyzer
extends org.apache.lucene.analysis.Analyzer

Since the ConfluenceAnalyzer does not handle filenames very well, we have a different Analyzer for that field. The main difference is the use of the FilenameFilter and LowerCaseFilter in addition to the StandardTokenizer.

The standard tokenizer kept parts of the filename and the filename extension together as one token. Therefore it was not possible to search for only the filetype or parts of the filename.
ConfluenceFilenameAnalyzer divides text at .-_ and converts them to lower case.

Example: will be tokenized into [file][name][java]
