= Xapian and MimeType Search with FindPage =
I'm using the Xapian search with pystemmer enabled and I like to search for mimetypes (with FindPage). But there are a few "problems". 
 * Tested on {{{ moin/1.6/rev/1829d890e862 }}}, but I think it's also valid for 1.7dev.

== Grouped MimeType Search from the FindPage form ==

--(A search for only the mimetype "application" doesn't work (with xapian/pystemer). but it should (this is also a bug report; [[MoinMoinBugs/XapianFindPageFormWorksOnlyForFullMimeType]], because the form FindPage offer this possibility).)-- fixed!

But now my wishes:
 * the text should be '''language specific''' and not only english
 * the mimetype groups should be '''configurable''' or a bit '''optimized''', because that a pdf-document counts to application is not very understandable for a normal user. It should look more like: documents [doc, odt, odf, odp, docx, xls, pdf, ppt,... ], application [exe,sh,..], archiv-files [tar,zip,bz2,..], images [png,jpg,gif,..], programming [py, c, h, ..] etcetera. 

== Finding the right MimeType is long winded with the FindPage form ==

If you want to find the correct mimetype e.g. for adobe pdf files - for what you looking for, adobe? pdf? No! You not even can type the first few letters of the wanted word (like a-d-o or p-d-f). the goal is to scroll down (a only three line field) ~'''400 entries''' and to looking for {{{ *.pdf - application/pdf }}}. this is not very userfriendly.

the list should be a drow down with possiblity to type the first letter (e.g. searching for pdf you would type {{{ p d }}} and find the correct file. So a listening should maybe look like:
 * {{{ <option value="application/pdf">pdf - application/pdf</option> }}}

== Finding only Wikipages with PageList or FindPage is complicated ==

Since the [[http://hg.moinmo.in/moin/1.6/rev/1829d890e862|Update]] from Thomas Waldmann its possible to search only for wiki pages (with the formater "wiki"); like 
{{{ 
<<PageList(python mimetype:text/wiki)>> 
}}} 

or also in the FindPage you can choose the correct mimetype. The link would look then something like:
{{{ 
http://moinmo.in/FindPage?action=fullsearch&advancedsearch=1&and_terms=moin&or_terms=&not_terms=&mtime=&categories=&language=&mimetype=text/wiki 
}}} 

But for an End-User it would be userfriendly if he can choose with a checkbox "no attachments" or "only wiki pages" (and this would search for only text/wiki). 
 * just implemented some ugly solution for a automatic search with "mimetype=text/wiki" only. see here [[ActionMarket/FullSearchMimeTypeSupport]].

=== Mimetype text/wiki vs. text/plain ===
There are maybe some future problems:
 * only search for text/wiki don't work if a user chose another formatter for a wikipage e.g. xml = text/xml.
 * if you search only for the "group" mimetype "text" then also some textfiles (text/plain) would be included (*.txt); so maybe the mimetyp text/wiki is not very "bright"; for pages it should maybe more look like wiki/<formatter> or moin/<formatter> 

this are just my 5cents; maybe with some better knowledge about the future "attachment" and storage framework there are other/better ideas and solutions available.
