In HIARCS Chess Explorer Pro there are up to 4 groups of games which some operations can be applied to:

  • Database - all the games in the database
  • Filter - only the games in the current search filter
  • Selection - this is a selection of games ticked in the Game Explorer game list.
  • Current game

Some functions operate on all four groups, while other's handle only the current game or some combination of game and filter.

When you first open a database the current filter is set to the entire database. When you search for games the resulting set of games becomes the new filter. In numeric terms the size of the filter is shown in the title bar of the Game Explorer view. 

This shows you that the Game Explorer is showing 58 out of 347,333 games. The current filter contains those 58 games.

There many ways to search for games that set the games filter you can read more about these in the Finding games section.

Although the filter is normally set as a result of a search you can add to the existing filter using the Header search.
