I tried searching for stuff and it returns nothing even when I searched the whole forum for the keyword ‘universe’ it returned nothing, is it not working at the moment ?

I have always wondered what this means, when we search;
“Keywords Stopped: universe”
?
I just did a search for a favourite - “multivalue” - and it worked alright.

What else did you try? I think “universe” is a “stop” word and hence you don’t get any hits for that. Dave, can you please confirm?
Also, please go through this link to understand the search capabilities.

I’ve tried XI and XI 3.0 and came up empty on both.

Answered here:
“XI” is too short
“3.0” is not indexed as it’s a number
The word “universe” is too common and therefore not indexed. It appears in nearly 40,000 posts on our board so far.
