I took backup of running site and setup in my development environment, when I rebuild custom indexes on staging (CM) under data/indexs folder I can see all files are updated but on production (CD) index files are not updated i can see it by their date and time modified and also by seeing only two initial files in the index folder.
As there is no any kind of change in config files index should be build what should i consider to check? I did not see any warning etc in log file.
I republished all items, and tried different strategies but no success.
