# I can't search on ^

I was trying to search for duplicates for this question: How to define the $0^0$?

But it's very hard to do this, as the search engine seem to ignore the ^ symbol. Searching for "0^0" or "0 0" give exactly the same answers. There seem to exist a duplicate, but it's almost impossible to find with the search engine.

• This is annoying, indeed. Ideally it would be nice to have the search engine go thru the TeX-sources. May be it cannot have access to those for technical reasons'? – Jyrki Lahtonen Dec 15 '12 at 22:40
• I can't even get Google to search for 0^0: "0^0" site:math.stackexchange.com – GeoffDS Dec 15 '12 at 23:25
• @Graphth Your Google keywords turn up that question for me as a second result. It's definitely not great, though. – Adam Lear ModStaff Dec 16 '12 at 1:07
• A very similar question: Search queries involving symbols and/or $\TeX{}$. Perhaps you will find something interesting in other question tagged search, too. – Martin Sleziak Dec 16 '12 at 13:29
• Since Google cannot search for caret symbol, you could include some keywords to help you find what you need. Something like: exponentiation "0^0" site:math.stackexchange.com. – Martin Sleziak Dec 16 '12 at 17:24
• Heads up, the new search engine will allow this search (I've tested internally), quoted phrases exact matches should help on math quite a bit it seems. We'll get the new engine rolled out to the network soon as we can. – Nick Craver ModStaff Dec 23 '12 at 22:48
• @Nick: thanks! That change is very useful. – Willie Wong Jan 7 '13 at 14:56

This search is now allowed, for example you can search for "0^0" or more relevant here since the start of it's latex: ["$0^0"][2]. We'll see how we can improve the "at the start/end of latex" since that $ delimiter gets in there as part of the term.
• That is wonderful. May I post a small request about LaTeX? It might be wise to discard {}` after all. Many people would write $\mathbb R$ and many others would write $\mathbb{R}$. The result is the same, and in fact is the same with $\Bbb R$ and $\Bbb{R}$. Whereas the latter requires some sleek comparison of "equivalent" commands, the former merely requires ignoring {} or finding a nice way to allow stripping them and comparing to the term asked for. – Asaf Karagila Mod Jan 7 '13 at 17:25
