How do the sort options work?

Sort options let you determine the order in which the summarized results appear.

Is there a maximum number of results I can get back all at once?

No. Click no limit next to Maximum returned if you want to see every match that your query finds. The intent of the default value (usually 500) is not to speed the search by limiting the scope but rather to restrict the initial results.

Is there a way to speed up a query?

Yes. Reduce the number in the Maximum Returned field. However, if the amount of time to return your query is prohibitive, consider narrowing your search rather than limiting the number of results returned.

The query is inclusive of the markers you enter.
