*	Fixed the thread index.	Christian Mollekopf	2018-06-19
\| \| \| \| \| \| \| \|	* Modifications could result in index changes because we lost the threadId due to remove + add. A modify was necessary (although we can ignore it for the email case). * The ThreadIndexer would try to lookup and potentially index threads for empty parent ids, which is clearly wrong.
*	Xapian based fulltext indexing	Christian Mollekopf	2018-02-11
\| \| \| \| \|	This cuts into the sync performance by about 40%, but gives us fast fulltext searching for all local content.
*	One central place to generate uids	Christian Mollekopf	2018-01-30
\|
*	Avoid reindexing the same thread	Christian Mollekopf	2017-09-12
\|
*	Implemented thread merging	Christian Mollekopf	2017-08-18
\| \| \| \| \|	It can happen that thread messages are not delivered in order, which means we will have to merge threads once all messages are available.
*	Added threading index cleanup	Christian Mollekopf	2017-06-15
\|
*	No more threading by subject	Christian Mollekopf	2017-06-15
\| \| \| \| \|	It seems to do more harm than good, creating huge threads, and the webclient doesn't do it either.
*	No more SINK_DEBUG_AREA	Christian Mollekopf	2017-05-12
\|
*	Gather required databases from index definitions.	Christian Mollekopf	2017-05-08
\|
*	Avoid threading messages by thread with empty subject	Christian Mollekopf	2017-03-06
\|
*	Debugoutput	Christian Mollekopf	2017-02-13

*	Fix threading for non-threaded messages.	Christian Mollekopf	2016-12-20
\| \| \| \| \|	Ensure we always have a messageId to work with, and avoid grouping all non-threaded messages together.
*	Get access to properties in indexes.	Christian Mollekopf	2016-10-21

*	A new indexer subsystem that can be used for indexes that are more	Christian Mollekopf	2016-10-21
