I receive an Index Server error 'Query Is Too Expensive', why?

A. If the content index is out of date, and you are executing queries that must be enumerated, you will get the above error message. To fix this problem wait until the index is up-to-date (it can be monitored through the Computer Management MMC snap-in in 2000) and perform the following steps:

  1. Edit the .idq file for the query and add the line
  2. Start the registry editor (regedit.exe)
  3. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex
  4. Double click MaxQueryExecutionTime and set to a higher value. Click OK
  5. Double click MaxRestrictionNodes and set to a higher value. Click OK
  6. Stop and start the Index Server service
