I have the following code to perform a full-text search. It creates a query, gets the total number of rows returned by that query and then retrieves the actual rows for only the current page.
// Create IQueryable
var query = from a in ArticleServerContext.Set<Article>()
where a.Approved
orderby a.UtcDate descending
select a;
// Get total rows (needed for pagination logic)
int totalRows = query.Count()
// Get rows for current page
query = query.Skip((CurrentPage - 1) * RowsPerPage).Take(RowsPerPage);
This works fine, but it requires two round trips to the database. In the interest of optimizing the code, is there any way to rework this query so it only had one round trip to the database?
