# Is there a limit on the length of queries for the oracle?

Consider the class $L^A$ which contains all the languages that are decided by a deterministic Turing Machine that uses $O(log(n))$ space and that can make queries to an oracle that decides $A$. My question is what is the length of query that the machine can ask the oracle? Is it $O(log(n))$ or can it be polynomial in $n$ (where $n$ is the length of the input)?
