> InvalidTokenOffsetsException when using MappingCharFilterFactory,
> DictionaryCompoundWordTokenFilterFactory and Highlighting
> ---------------------------------------------------------------------------------------------------------------------------
>
> Key: SOLR-2891
> URL: https://issues.apache.org/jira/browse/SOLR-2891
> Project: Solr
> Issue Type: Bug
> Components: highlighter, Schema and Analysis, search
> Affects Versions: 3.1, 3.4
> Environment: MacOS X, Java 1.6, Tomcat 7
> Reporter: Edwin Steiner
> Assignee: Robert Muir
> Priority: Critical
>
> I would like to handle german accents (Umlaute) by replacing the accented
> char with its two-letter substitute (e.g ä => ae). For this reason I use the
> char-filter solr.MappingCharFilterFactory configured with a mapping file
> containing entries like "ä" => "ae". I also want to use the
> solr.DictionaryCompoundWordTokenFilterFactory to find words which are part of
> compound words (e.g. revision in totalrevision). And finally I want to use
> Solr highlighting. But there seems to be a problem if I combine the char
> filter and the compound word filter in combination with highlighting (an
> org.apache.lucene.search.highlight.InvalidTokenOffsetsException is raised).
