When indexing items initially, the generic
provider listens for mutations in case an
item's composition changes, so it can then
index the new children.
Changed the controller to update the tree
display status when the search result
promise is fufilled, not before making the
search query.
Also chagned the loading increment from
5 to 20.
Moved the elasticsearch provider to
platform/persistence/elastic. Then moved
the search aggregator and the generic
provider into a services folder within
the search folder.
Slight tweak to the padding of the search view,
which affects where the top of the scroll bar
appears. Also removed the search scroll div
because it was unused.
The controller's loadMore function now sends
new queries to the search service if the
controller's full results list does not have
enough results in it to load more.
The elasticsearch provider returns an empty
result when elasticsearch throws an error
(probably a bad request). This prevents the
aggregator from thinking that ES is loading
infinitely.
The aggregator now returns a result object similar
to that of the providers, but the hits array contains
domain objects rather than searchResult objects.
Also removed overly complicated filterRepeats
function from the aggregator and replaced it with a
simpler one.
The provider now returns an object that has
a hits property which contains what it
previously returned, and also a total property
which contains the total number of results.
Removed the name field from the ElasticSearch provider
search query string, so now it will check all of the
fields of the domain object (such as type).
Updated comments and documentation. Changed the generic
worker to return results as {id: score} key value pairs
rather than {id: {score: score}} format. Removed unused
getLatestResults and getLatestTimestamps functions from
the providers.
Removed the timestamp as an optional parameter
of the search aggregator's query(), and now it
instead automattically generates one before
querying the providers.
Also attempted to fix loading, but did not
complete (commented out).
The search service's interface now just consists
of the two functions query() and isLoading().
query() returns a promise for an array or results,
which eliminates the need for timeout polling like
was previously done. The search providers
have also been changed to reutrn promises.
