Autoindexer does not index documents in the file directory

[CR #339901] The autoindexer does not index the documents you have in your file directory.

Workaround:

Make file access permission changes to the <Autonomy_Install_Dir>/autoindexer file:
```
cd <Autonomy_Install_Dir>/autoindexer/filters
chmod 777 *.exe
cd <Autonomy_Install_Dir>/autoindexer
```
where <Autonomy_Install_Dir> is the location where you installed Autonomy.

Clear out the runtime status files:

cd <Autonomy_Install_Dir>/autoindexer/
rm *dirstat* cd

Stop and restart the autoindexer.
