when I press the Question mark button it shows V9.0, Finally in the web.config file I found this line:
<add key="CMSProcessSearchTasksByScheduler" value ="true" />
and I removed it to disable the scheduler, it rebuilt but shows:
Indexed items: 1009
Index file size: 2 MB
Index status: Ready
Optimized: Yes
Last update: 10/31/2017 12:41:44 PM
Last rebuild: 10/31/2017 12:41:44 PM
but when testing the search it does'nt return anything, noting that the indexed content is all pages (I added "/" for all pages and "/%" for all sub pages) compared to the index file size: 2MB, something is wrong right? does it affect the results if the structure of the project is template based and not web part based?
