Orpahned segments that cannot be force merged

[Slav Boleslawski <sl...@hotmail.com>]

Hi,


I can control the number of index segments when indexing using forceMerge(), but when searching occurs during indexing, then some segments become orphans and cannot be force merged. Why?Could someone please have a look if I'm doing anything wrong.


I attach the complete code for a test case to show the problem. The details are in the code documentation.


Regards

Hi,

 

Hi they are not orphans, they are just used still by the index reader. The operating system prevents them from being deleted as long as an index reader is open on them. Once you are done with forceMerging, you have to reopen your index reader (e.g., using SearcherManager). The files will disappear after a while.
