The Attachment Search Tool
When a WikiWiki is used for professional documentation purposes there will be a time where someone does the quick and dirty "I put this PDF as an attachment in it" trick. The standard Wiki does not search in such a document. Here is an example for solving this problem.
The Attachment Search Tool has three components:
the /CacheGenerator for creating word lists of the attachments (doing it in real time is too slow for many docs)
the /AttachSearch macro for creating a search form
the /attsearch action for doing the search stuff
Because this is the first real Macro/Action thingie I developed it may be not perfect - so if there is someone who likes to enhance it: The code is GPL!
If you enable Xapian you can search in a lot of mimetypes.
