Dear all,
At the path of /var/confluence/index/plugin/usage, I can find index file as listed as below:
-23*92.fdt,
-23*92.fdx
-23*92.fnm
-23*92.frq
-23*92.nrm
-23*92.prx
-23*92.tii
-23*92.tis
-23*92.cfs
-23y6g.cfs
-23y6h.cfs
segments_1kzp0
segments.gen
But sometime the files of -23y6g.cfs, -23y6h.cfs is gone, why they are disappear? We must refresh the path several times, and it will show again.
