Greg Kable updated JSPWIKI-528:
-------------------------------

    Attachment: jspwiki-528-SearchProviders.patch

Patch 3 - org.apache.wiki.search.

- Changed BasicSearchProvider, LuceneSearchProvider and SearchProvider to 
return an ordered List and updated Javadoc to match.  Why List instead of 
SortedSet you ask? In this case using SortedSet would require repacking and 
re-ordering results from 3rd party search engines (e.g. Lucene) whereas List 
simply preserves the underlying order.

> Rationalise the use of Collections, particularly with regard to pages

> Most of the APIs return Collection rather than a finer interface and in many 
> cases these collections are repeatedly repacked and resorted unnecessarily. I 
> will go through all APIs that return collections of pages and make them 
> return a finer interface - probably List for unordered collections and 
> SortedSet for ordered collections. This will make the use of these 
> collections much clearer for further development and give us some opportunity 
> for future optimisations.
> This is likely to be a very wide set of changes across lots of different 
> classes so I'll submit separate patches for each class.
