CONTAINSTABLE v/s FREETEXT


A

Abhijeet Raje

Hi All,
I have one table Customers in Northwind database.
While performing FreeText search I want to give weightage ON Columns for
a searched phrase.
CompanyName weight (1) ContactName weight
(.7)
ContactTitle weight (.5) Address
weight (.5)
If I Searched for "Christina" phrase then results will be displayed base
on weightage as well as rank.
i.e. results having "Christina" in CompanyName should be displayed
first. If I found "Christina" only in Address then this should be last.

Any Ideas???

Regards

Abhijeet

Abhijeet,
First of all, all of the tables in Northwind are much too small for proper
consideration of the understanding of CONTAINS* vs. FREETEXT*, in the same
manner as you would not use the Northwind database for performance
benchmarking of production databases. Note, FREETEXT ignores Boolean
comparisons. You need a statistically significant number of rows (100K+) as
well as a significant number of non-noise, unique words for your testing to
give valid results.

Also, since you're trying to "weightage ON Columns", you should review KB
articles: 286787 (Q286787) FIX: Incorrect Results From Full-Text Search on
Several Columns
http://support.microsoft.com/default.aspx?scid=kb;en-us;286787 and 294809
(Q294809) FIX: Full-Text Search Queries with CONTAINS Clause Search Across
Columns http://support.microsoft.com/default.aspx?scid=kb;en-us;294809. This
is the default behavior for SQL Server 2000 as well.

John
