Searching for $C^*$
@Turbo: No as '\' does not act as an escape character and '\*' returns a parsing error.

Searching for $C^*$
@quid: I have written to tech support and got an answer which works reasonably well for the specific phrase "$C^*$algebras", but not for example, for "$C^*$", or "$*$category". I have asked for clarification for these other cases and (assuming no one else on MO has an answer) will post whatever information I get back.

Accuracy of the truncated Hausdorff moment problem
@Sergei: Most of what I found regarding the error seemed to be giving upper bounds on the error (i.e. a given method won't be worse than X), when I am looking for lower bounds on the error (i.e. you can't hope to do better than X). That said I would bet that among the many references there probably is one which answers my question. However being very far from an expert in this area I wasn't able to find an appropriate result after several hours of looking. Although I am hoping it would be easy/immediate to an expert.

Accuracy of the truncated Hausdorff moment problem
Thanks. However I am specifically interested in the case when the range is contained in a fixed bounded set (e.g. $[0,1]$)

Does $Add(\kappa,1)^L$ ever collapse cardinals?
@Asaf: Thanks. But then this raises three other questions. First, why is this $Add(\kappa, 1)$ and not $Add(\kappa, 2)$? What is $Add(\gamma, \kappa^+)$? And then what is the difference between $Add(\kappa, 1)$ and $Add(\kappa, 1)^L$ (which is mentioned in the question as separate)?

What is the partial order for $Add(\kappa, 1)$?

Theory of C* algebras over other fields than the complex numbers
Thanks, this is very helpful. I am also interested in knowing if the theory of C*algebras generalized for algebraic closures of specific real closed fields (like for example the surreals)
