Are you installing from the ICA-AtoM tarball, or from an SVN
checkout?  There was a bug with the installer that prevented the
creation of search indexes in an early version of the 1.0.5 tarball
that should be fixed in the most recent version - this bug would
produce the errors you are seeing.

The method for fixing this error message is very straightforward:

1) First, make sure to delete all sub-directories within the "data/
index" directory of your local copy, as the existing indexes may be
corrupt.

2) At the command line run the following symfony task to rebuild the
search index for each language/locale with translations in ICA-AtoM:
 > php symfony search:populate de
 > php symfony search:populate en
 > php symfony search:populate es
 > php symfony search:populate fa
 > php symfony search:populate fr
 > php symfony search:populate it
 > php symfony search:populate nl
 > php symfony search:populate pt
 > php symfony search:populate sl

You should see a message like this for each language:
en >> Populating index...
en >> Index erased.
en >> Found 0 services.
en >> Index populated in 0.05 seconds.
en >> Optimizing index...
en >> Index optimized in 0 seconds.

3) Re-run the installer, or manually load data into the database with
the following command:
