Markus Jelsma updated NUTCH-1262:
---------------------------------
Description:
Similar or duplicating content-types can end-up differently in an index. With,
for example, both application/xhtml+xml and text/html it is impossible to use a
single filter to select `web pages`.
See also:

Content-Type mapping is disabled by default and is enabled via
moreIndexingFilter.mapMimeTypes. Example mapping file is provided in conf/.
{code}
# target MIME-type <TAB> type1 [<TAB> type2 ...]
# Map XHTML to HTML
text/html application/xhtml+xml
# Map XHTML and HTML to something else
Web page text/html application/xhtml+xml
# Map some office documents to each other
Office document application/vnd.oasis.opendocument.text
application/x-tika-msoffice
{code}
