Can anyone tell me how to search a particular question in the forum using the search bar. I have tried many times searching (for eg) Q10.12 but the search ends with 'No results found' , but when i check on the posts by navigating, i see the keyword Q10.12 in the post.
That does seem strange. I guess the way round it is to search more generally, eg for "Chapter 10" or some key words on the topic you're interested in.
