If you are encountering problems with Big or Mega 2008, in the sense that specific
positions you know are in the database are not being retrieved by ChessBase
using the search mask or Shift-F7 ("Find position in Mega Database"),
this may be the result of a faulty or incomplete search booster. To cure the
problem you should perform the following steps. It is advisable to do so even
if you haven't encountered any problems, as you may simply not have noticed
that any existed.
Mega Database 2008 contains 3.75 million games, from 1560 to 2007, of which
61,000 contain analysis. Big Database contains the same number of games but
without the analysis. When you ask the program ChessBase whether a specific
position has occurred before, it is essentially searching through about 300,000,000
positions. In order to increase the search speed through such a large volume
of data the program uses a "search booster". This is a file that contains
preprocessed information that would otherwise be repeated during each search.
If the search booster is damaged or incompletely installed the program may
have problems finding certain positions. Here is how you can repair it:
Highligh Mega Database in your database window. Use "Tools –
Database – Delete Search Booster" to delete the current booster,
and then "Tools – Database – Create Search Booster"
to create a new one. The whole process will take a couple of minutes.
Click on the Mega Database 2008 icon on your ChessBase database window to highlight
it. If you have the "Details" view switched on it will look like this:
Now go to the Tools menu and use "Database – Delete Search Booster"
to, well, delete the search booster.
Astute readers will have guessed the next step:
Yes, "Create Search Booster". This should take just a few minutes:
After that you are fine to go. You may want to check one more thing: that Mega
2008 is your "Reference Database." This simply means it is the default
place to look for information.
Right-click Mega Database 2008 and click "Properties" in the context
menu that appears.
Make sure that Mega Database 2008 is your reference database (checkbox clicked
