Re: Set analysis difference between single quote and double quote
Today there is no difference between using single or double quotes (or [...] or `...`). They will all be interpreted as quotes defining a search and not a literal match.
But just as stalwar1 points out - it is a bug. Fixing it was more complicated than we thought, so it has still not been fixed. But we are working on it right now and my guess is that we will have it fixed soon.
In the future it will work like this:
Double quotes: Case insensitive search where * and ? are interpreted as wildcards
Single quotes: Case sensitive string match where *, ?, =, > and ~ all are treated as any characters
