title: What are the query length limits for the Bing WebSearch API?
body: <p>Given that the Bing API docs consist primarily of an error-ridden, two-page Word document, I have not been able to find the answer to this online.  Trial and error has produced inconsistent results, and given that queries cost money, I'd rather not have to guess and check any more.</p>
  
  <p>What are the length limits are on the new 'Azure marketplace' Bing WebSearch API?  I know there is a limit of some sort, because long queries tend to return, "The request was not accepted by the data provider's service. The team is investigating the issue. We are sorry for the inconvenience."  However, the query length at which this occurs, both in terms of characters or words, tends to vary based on the query entered.  I am using fairly complex queries with advanced operators like site: and instreamset:, so it is very difficult to narrow down what the limitation is.  ie: I have successfully made queries of over 1800 characters, and I have had them fail with less than 1200 characters.</p>
