Use PDF-4 or PDF-2 as Reference Database

Note: The ICDD PDF relational database products (like PDF-4+, PDF-2 starting with release 2005 etc.) are currently only available for the Windows platform. Hence, you cannot use these databases if you are running Match! on a Mac or Linux machine!

Using the ICDD PDF database products with Match! is pretty easy: Simply install the PDF database on your Windows PC according to the instructions given by ICDD, then launch Match!.

Match! will automatically detect newly installed PDF database products at program startup (at least if the corresponding option is set) and ask if you would like to index one of them straight away. If you agree by clicking "Yes", the database indexing will be performed immediately. You will then be asked if you would like to use the new reference database straight away. You can do so by clicking "Yes" again. That's it!

Please note::

You can also perform the indexing of a PDF database manually, of course. In the following, we will demonstrate how to apply an existing ICDD PDF-4 or PDF-2 database as a Match! reference database:

Let us assume that you would like to add the ICDD PDF-2 Release 2018 database (which must of course have been installed already) (the procedure for using the corresponding PDF-4 is the same):

First, please open the Reference Database Library, and press the "Create" button at the bottom. You now have to tell Match! that you would like to use an ICDD PDF database, by marking the checkbox "ICDD PDF" in the upper part of the "Create Reference Database" dialog. Afterwards, you must select which PDF database you would like to use. In our case, we would like to use the PDF-2/Release 2018, so please mark (click on) the corresponding line in the list below "ICDD PDF".

If you like, you can change the name of the new reference database at the bottom of the dialog (deactivate the corresponding "Automatic" checkbox first!), and/or change the location (directory) in which the index files for the new reference database shall be stored. Normally, Match! will automatically create a suitable name and select an appropriate directory.

In case you have administrator privileges, you can also select if you would like to make the new reference database available to all users (or only to you), and if you would like to make it the default Match! reference database for new users on your PC.

Please note that on Windows it is not sufficient to run Match! from an administrator account; you have to explicitly use the command "Run as administrator" (which is available e.g. in the context-menu (click right mouse button)) in order to enable the two options "Create for all users" and "Select as default for all users without own selection"!
On Linux, you have to use "su" or "sudo" in order to run Match! with "root" privileges and enable these two options.

Once you have made your selections, press the "OK" button at the bottom to start the creation of the index files. A small window will display the progress of the indexation. Due to the large amount of data which have to be read and sorted, the creation of index files is a rather time consuming process. The procedure may take between a few minutes to an hour or even more, depending especially on the drive access and processing speed of your computer.

When the indexation has finished, a corresponding message will be displayed. Afterwards, the new reference database will appear in the Reference Database Library.

If the new reference database is the only one available in the Reference Database Library, it is selected for being used automatically. Otherwise, you have to select the new reference database manually.
