When I'm logged in and I search for
[tikz*] I obtain as result
[tikz-pgf] or [tikz-styles] or [tikz-arrows] or [tikz-trees] or [tikz-external] or [tikz-cd] or [tikz-qtree] or [tikz-matrix] or [tikz-3dplot] or [tikzposter] or [tikz-node] or [tikz-graphs] or [tikzmark] or [tikz-pic] or [tikz-feynman] or [tikz-uml] or [tikz-shape] or [tikz-circuit-lib] or [tikz-graphdrawing] or [tikzscale].
But when I'm not logged in and I search for the same
[tikz*] I obtain as result only
[tikz-pgf] or [tikz-styles] or [tikz-arrows].
Any idea why this difference ?
Edit: I tried to search for 4 tags when logged off, and my query was cut down to 3 tags. So probably this is related to maximal number of tags that non logged user can use in a query.
