Hi,
 I have configured MOSS search using BDC.
I am trying to change the search relevance settings for the managed properties.
I have tried resetiing weight proprty, but it is not taking affect.
How to improve relevance for managed properties in MOSS?

Is there other ways to do that?

Thanks in Advance

How did you set the weight property? Did you use the code sample on MS (http://msdn2.microsoft.com/en-us/library/ms553069.aspx). Are you sure it took, there is a bug in the sample, they forgot to call update.

What number did you actually set it to? The Title property is the default highest at around 75.

Hi, Thanks for the reply.

I am using the following code to update the weight property for one of the managed property.

I just did a quick test and verified that the changing of the properties effect is immediate, no need to do an iisreset or restart the search service.

Quick question. Is Customer Name marked as the Title in your BDC definition? If yes then try setting the weight to 100 to be greater than the Title weight.

Hi,
I really appreciate your help.
I have tried setting the weight to 100 for the FrequentItems managedProperty, but still in Search results most relevant and least relavant results are mixed in the top results.
And I have checked in y BDC metatadata file, and found that CustomerName is marked as title in that.
I suspect this might be the reason, the most and least relevent results are mixed up in the top search results.
So I have tried resetting the Title weight to "0" from 75.855(default weight for Title).
Now I am able to see the results in the way that I wanted.
But if I am going to follow this approachand reset the Title weight to zero, then it will affect even All Sites search and any other search on that site, as Title is the Default managed property.

Is there any other way that I can get the most relevant results in the top results, without resetting the Title weight to zero and keeping CustomerName marked as Title in BDC? If not is there going to be any effect if I remove the line of code which is marking "CustomerName" as "title"? Currently on my Business DataList webpart, in the data retrieved for CustomerName I am getting the action URL as "Customer Details", will this be affected?

<Properties>

<Property Name="DefaultAction" Type="System.String">Customer Details</Property>

</Properties>

</Entity >

I have one more query, I have a crawled property exposed by BDC, but there is no Managed Property defined for that.
But still I am able to search based on that crawled property. Now I want to improve the Search relevance for that crawled property also.

To improve the relevance is it mandatory to create the managed property for the crawled property exposed by BDC?

Thanks.

Try setting the title back to 75.855 and then set the FrequentItems to 10000. This should overpower the relevancy of Title when FrequentItems Exists. The weight value can go higher than 100. I have modified my freeware tool at http://sharepointsearch.com/cs/files/folders/searchtools/entry2527.aspx to have a limit of 10000 now not 100.

You need to have a title or else the data won't display properly in search results or web parts.

The reason you are able to still search on that property is because its content is in the full text index along with all the other metadata for that BDC item. There are of course many other things involved in determining relevancy besides property weighting, like term frequency and nearness of words, so I suppose you could create like 50 different variations of that same column. eg. <Property Name="FrequentItems1" Type="System.String">FrequentItems<Property><Property Name="FrequentItems2" Type="System.String">FrequentItems<Property><Property Name="FrequentItems3" Type="System.String">FrequentItems<Property>  so that in the full text index the terms would appear more frequently for the given item.

Hi,

Thanks for the information. I will try out this solution.
