Conditions in ANY queries can be made required by passing 'true' as an extra parameter to addCondition() and updateCondition() -- this can be used for limiting ANY queries to particular collections (in place of the removed 'context' condition), but if there was an elegant way to expose it to the user for all ANY queries, it's something users might find very useful.
- Implemented 'collectionID' and 'savedSearchID' conditions (a.k.a. search within a search) and removed special 'context' condition. Per my conversation with Dan, the 'recursive' flag is now a global flag that applies to all specified collectionIDs, which is less than ideal but probably better than the alternatives (e.g. having condition-specific recursive checkboxes). It does mean, however, that a "Search subfolders" checkbox is irrelevant if there are no collectionID conditions and should probably be greyed out until applicable.
Another side effect is that it's no longer possible to do an ANY search and return results only within a specific folder (though it can now be done by putting the ANY conditions in a subsearch). Since ANY searches are always annoying in this regard, what I might do is add a way to mark particular conditions as required even in ANY mode, which would allow for quite a lot of flexibility...
Note also that while 'collectionID' and 'savedSearchID' are standard conditions, they should probably be combined into a single condition on the interface side (like playlists and smart playlists under just 'Playlist' in iTunes).
- Now skips invalid/obsolete saved conditions in load()
- Remaining searchConditionIDs are no longer affected by removeCondition() (i.e. they now act like autoincrements), which should make interface code simpler
- Changed default join mode to ALL
- Fixed loading of saved searches with no search conditions
Implemented advanced/saved search architecture -- to use, you create a new search with var search = new Scholar.Search(), add conditions to it with addCondition(condition, operator, value), and run it with search(). The standard conditions with their respective operators can be retrieved with Scholar.SearchConditions.getStandardConditions(). Others are for special search flags and can be specified as follows (condition, operator, value):
'context', null, collectionIDToSearchWithin
'recursive', 'true'|'false' (as strings!--defaults to false if not specified, though, so should probably just be removed if not wanted), null
'joinMode', 'any'|'all', null
For standard conditions, currently only 'title' and the itemData fields are supported -- more coming soon.
Localized strings created for the standard search operators
API:
search.setName(name) -- must be called before save() on new searches
search.load(savedSearchID)
search.save() -- saves search to DB and returns a savedSearchID
search.addCondition(condition, operator, value)
search.updateCondition(searchConditionID, condition, operator, value)
search.removeCondition(searchConditionID)
search.getSearchCondition(searchConditionID) -- returns a specific search condition used in the search
search.getSearchConditions() -- returns search conditions used in the search
search.search() -- runs search and returns an array of item ids for results
search.getSQL() -- will be used by Dan for search-within-search
Scholar.Searches.getAll() -- returns an array of saved searches with 'id' and 'name', in alphabetical order
Scholar.Searches.erase(savedSearchID) -- deletes a given saved search from the DB
Scholar.SearchConditions.get(condition) -- get condition data (operators, etc.)
Scholar.SearchConditions.getStandardConditions() -- retrieve conditions for use in drop-down menu (as opposed to special search flags)
Scholar.SearchConditions.hasOperator() -- used by Dan for error-checking
