+> One problem is that the

+> for the XML file contains a number of silly limits to field lenghs.
+> For example, it wants a "ShortName" that identifies the search engine,
+> to be 16 characters or less. The Description is limited to 1024,
+> the LongName to 48. This limits what existing config settings can be
+> reused for those.
+>
+> Another semi-problem is that the specification saz:
+>
+>> OpenSearch description documents should include at least one Query element of role="example" that is expected to return search results. Search clients may use this example query to validate that the search engine is working properly.
+>
+> How should ikiwiki know what example query will return actual results?
+> (How would a client know if a HTML page contains results or not, anyway?)
+> Sillyness. Ignore this? --[[Joey]]
