Here was the situation: my fast search crawl seemed to be
running fine. There were no crawl errors reported in Central Admin under the
crawl content sources listed under the FAST Connector. However, I was not getting
any results dated after Jan 12, 2013 (at the time of this post is it August
2013). Obviously something was wrong. I uploaded a new document within a
document library. I ran an incremental crawl. I could see in CA that the
document was crawled, but again when I searched for that document on the site,
my new document did not return in the results.
I reset the index and still no luck. I’ve been working on
this off and on for a while now. Finally tonight, I was successful in
discovering the answer.
My index was stuck! Here’s how to find out if your index is
stuck.
Determine If Your Index is Stuck
On your FAST server, open a CMD prompt, Within the directory
for your FAST install, there are some tools to help you. In CMD, type c:\FASTSearch\bin\indexerinfo
status (this is the default install location, yours may be different. You will get some xml output. The important
line is near the top and will say something like
documents indexed="0" not_indexed="692711" size="721755503316.000000" total="692711"
Notice the part in that line about “not_indexed.” So even though my crawl was good, my index was
stuck.
Resume and Reset Indexing in CMD
Next step is to run the following in CMD (use the location of
your FAST install, default is shown below):
C:\FASTSearch\bin\indexeradmin resumeindexing
This works for some people to get the index unstuck. But
that didn’t work for me. Next step, in CMD:
C:\FASTSearch\bin\indexeradmin resetindex
Running this line made it so that all of a sudden I had NO
results coming back for searches. Yikes!!
Reset and Clear the Index in Central Admin
So I cleared out the index with the following steps:
1.
Make sure the account performing this is a
service application administrator for the FAST Content SSA
2.
Go to Central Admin à Application Management à
Manage Service Apps
3.
Click the FAST Content SSA
4.
On the Search Administration Page under Crawling,
click Index Reset
5.
Click OK
Before any new crawls are started you must manually clear
the content from the content collection.
1.
Log onto your FAST server
2.
Open the Microsoft FAST Search Server 2010 for
SharePoint shell as administrator
3.
Type the following command
Clear-FASTSearchContentCollection
–Name sp*
4.
Wait for it to finish, it will most likely take
quite a bit of time.
*The name of the content
collection could vary. To get the name of your FAST search content collection,
in FAST powershell type
Get-FASTSearchContentCollection
Voila! Success! I have results and they are current now.
Yay!
