    <p>First off there seems to be no way to get an exact match using a full-text search. This seems to be a highly discussed issue when using the full-text search method and there are lots of different solutions to achieve the desired result, however most seem very inefficient. Being I'm forced to use full-text search due to the volume of my database I recently had to implement one of these solutions to get more accurate results.</p> <p>I could not use the ranking results from the full-text search because of how it works. For instance if you searched for a movie called <code>Toy Story</code> and there was also a movie called <code>The Story Behind Toy Story</code> that would come up instead of the exact match because it found the word <code>Story</code> twice and <code>Toy</code>.</p> <p>I do track my own rankings which I call "Popularity" each time a user access a record the number goes up. I use this datapoint to weight my results to help determine what the user might be looking for.</p> <p>I also have the issue where sometimes need to fall back to a LIKE search and not return an exact match. I.e. searching <code>Goonies</code> should return <code>The Goonies</code> (most popular result)</p> <p>So here is an example of my current stored procedure for achieving this:</p> <pre><code>DECLARE @Title varchar(255) SET @Title = '"Toy Story"' --need to remove quotes from parameter for LIKE search DECLARE @Title2 varchar(255) SET @Title2 = REPLACE(@title, '"', '') --get top 100 results using full-text search and sort them by popularity SELECT TOP(100) id, title, popularity As Weight into #TempTable FROM movies WHERE CONTAINS(title, @Title) ORDER BY [Weight] DESC --check if exact match can be found IF EXISTS(select * from #TempTable where Title = @title2) --return exact match SELECT TOP(1) * from #TempTable where Title = @title2 ELSE --no exact match found, try using like with wildcards SELECT TOP(1) * from #TempTable where Title like '%' + @title2 + '%' DROP TABLE #TEMPTABLE </code></pre> <p>This stored procedure is executed about 5,000 times a minute, and crazy enough it's not bringing my server to it's knees. But I really want to know if there was a more efficient approach to this? Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
