Error: HRESULT E_FAIL has been returned from a call to a COM component

I was working on an Enterprise Search deployment the other day and I encountered this lovely error. I found the answer buried in some forum posts, but I wanted to tell you what side effects I found when implementing the solution (and I wanted to make sure I could find the answer again someday when I...

Profile Import Error: The specified domain either does not exist or could not be contacted. (Exception from HRESULT: 0x8007054B)

The other day, I had an issue importing User Profiles and Properties from Active Directory. In this case my MOSS server is on a child domain and it could import the child domain's objects, but it could not import the objects from the parent domain. Checking the log, I saw an error like the following...

Tracing Service lost trace events

If you are like me, you go to the SharePoint logs folder often in an attempt to try and resolve various errors you may encounter when working with SharePoint. I noticed on some of my servers, that I was receiving an entry similar to the one below in my log file. 04/17/2008 10:45:52.99 wsstracing.exe...

Don't forget to set your row limit

Recently, I wrote my own control to allow drilldown on Facets for one of our Enterprise Search pages, and someone pointed out to me that it never returns more than 50 results. It was then I remembered seeing a RowLimit property on the KeywordQuery and FullTextSqlQuery classes. I first checked the SDK...

Using LINQ to make Enterprise Search Results more usable

In my previous post about using the KeywordQuery class, I had one small omission. The fact is that when you add your own managed properties using the SelectProperties collection of the keyword class, the data type you get back is a string[] containing 1 element instead of a string. This can be quite...

SharePoint Developers are Developers too!

I am sure many of you have faced a situation like this yourselves. You meet some new developer and they ask you what you do and you tell them that you are a SharePoint developer and they are like "Oh. That's nice." I have to admit before I started doing SharePoint, I may have been guilty...

How to: Specify a Content Source using the Keyword Syntax

At some point you may want to do an Enterprise Search query and specify that the results come from a particular content source. A lot of times you might create a custom scope with that content source in it, but if you don't want to create a new scope, you can just query the content source directly...

Specifying Scope(s) with the KeywordQuery class

Today I realized that when I blogged about how to use the KeywordQuery class, I forgot to mention how to specify the scope(s) you are querying. You would think there would be a built-in property to set this, but there isn't. I wanted to see how Microsoft was doing it so I used reflector and examined...

How to: Use the MOSS Enterprise Search FullTextSqlQuery Class

A while back, I posted a how to on using the KeywordQuery class and it seemed to get pretty good response, so I figured I would post a follow up on how to use the FullTextSqlQuery class today. It's actually pretty similar to using the KeywordQuery class but of course the syntax is different. I am...

How to: Create a Scope Display Group using the API

Yesterday, I talked about an issue with the SearchBox Web Part resulting from not having the Scope Display Group it used defined on my site collection. I mentioned, the best way to fix this was to have your feature create the scope display group for you, so here is how its done. To accomplish this, you...
