There is a store procedure that uses FREETEXTTABLE twice on two tables and then merges the results and returns the top 50. The problem is if I do a search on "Women of Brewster", the results returns "Confession of an ex doofus motha" with a rank of 143 from table A and second "Women of Brewster Place" with a rank of 102 from table B. Is this because of the count? (Table A return results total is 2399. Table B return results total is 3445.) The short answer: Freetext ranking is based on the OKAPI BM25 ranking formula. Each term in the query is ranked, and the values are summed. Freetext queries

The Product table has 700K records in it. The query: SELECT TOP 1 ID, Name FROM Product WHERE contains(Name, '"White Dress"') ORDER BY DateMadeNew desc takes about 1 minute to run. There is an non-clustered index on DateMadeNew and FreeText index on Name. If I remove TOP 1 or Order By - it takes less then 1 second to run. Here is the link to execution plan. http://screencast.com/t/ZDczMzg5N Looks like FullTextMatch has over 400K executions. Why is this happening? How can it be made faster?

Is it possible to order results in SQL Server 2005 by the relevance of a freetext match? In MySQL you can use the (roughly equivalent) MATCH function in the ORDER BY section, but I haven't found any equivalence in SQL Server. From the MySQL docs : For each row in the table, MATCH() returns a relevance value; that is, a similarity measure between the search string and the text in that row in the columns named in the MATCH() list. So for example you could order by the number of votes, then this relevance, and finally by a creation date. Is this something that can be done, or am I stuck with just

I see that Entity Framework core 2.1 has a new feature to use FREETEXT , but I am not sure how to use it as there are no examples that I can find online. https://github.com/aspnet/EntityFrameworkCore/issues/11484 Has anyone used it yet and could give me a quick example? First make sure you have the relevant packages installed Microsoft.EntityFrameworkCore and Microsoft.EntityFrameworkCore.SqlServer . Then ensure you have the following import: using Microsoft.EntityFrameworkCore; Now you can use the FREETEXT SQL function like this: var results = context.Foos .Where(f => EF.Functions.FreeText(f

I have SQL server 2008 r2 edition, which am working on and a .Net webpage as front end. Coming to the issue, there is a column in the database which basically consists of various skill sets separated by a comma. For example some candidate has a 3 different skill sets namely C# , SQL server , Oracle . The user who wants to list the candidates having the skills of both C# and Oracle will provide the input as C#, Oracle in a text box on the webpage. I want to write a query which can list out such. I have tried freetext search. But it fails to fetch if in Capital/small words, no support for
