PDFlib TET PDF IFilter 4.0 Manual

Predefined properties. A column definition file for all predefined properties (see Appendix
A, »Predefined Metadata Properties«) is installed with TET PDF IFilter. It can be
configured according to the steps described in the next section. Although the property
definitions are built into TET PDF IFilter, you must enable the desired property set collections
in the XML configuration file (see Section 3.3, »Predefined Metadata Properties«,
page 41). Using this column definition file for all predefined properties is a convenient
method to see which properties are actually found in your documents since only detected
properties will be displayed in the management console.
XML configuration for Indexing Service. Table 3.10 lists requirements and recommendations
related to the XML configuration for TET PDF IFilter when working with Indexing
Service.
Table 3.10 XML configuration for Indexing Service
element attribute requirements and recommendation
Property emitAsVector Must be false for properties which may have multiple values if the property’s
type attribute is different from String (see Section 3.5, »Multivalued
Properties«, page 44).
Configure custom metadata properties. Proceed as follows to prepare custom metadata
properties for indexing; some steps are not required for predefined properties but
only for custom properties:
> (Not necessary for predefined properties) Create configuration entries for TET PDF
IFilter in the XML configuration file (see Section 3.4, »Custom Metadata Properties«,
page 42).
> (For predefined properties use the column definition file which is installed with TET
PDF IFilter) Create a column definition file with property descriptions according to
the description in »Create a column definition file«, page 59.
> Click Start, Run..., and type regedt32.exe to launch the registry editor. Navigate to the
following entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndexCommon
Locate the key DefaultColumnFile. If this key exists (which may be the case if you have
Windows Search installed) note the file name it contains. A typical value is
C:\Documents and Settings\All Users\Application Data\Microsoft\
Search\Config\msscolmn.txt
If the key exists, you can edit the existing text file at that location in the next step. If
the key does not exist, click Edit, New, String Value to create it, and add a full path
name pointing to the configuration file created in the next step.
> Edit the existing text file msscolmn.txt (or create a new one at an arbitrary location, as
appropriate), and insert the property definitions prepared earlier.
> Rebuild the catalog. Make sure that for each configured property at least one file has
been indexed. Properties will only be available for the next configuration steps if
they have been picked up during the indexing process.
> Navigate to Services and Applications, Indexing Service, System, right-click on Properties,
and select All Tasks, Refresh List. For each property found in the indexed documents a
separate line will be displayed. You can identify properties by their GUID in the first
