5.2.2.1 DB: Searchmask

Upon entering this choice your screen will change into a form where you can mark several selection possibilities. Press on the "SEARCH" button after you have defined you search items and the database will be searched for games that meet your specifications.

First of all you'll have three vertical rows of blocks that can be switched on/off. You can only have one of those three activated per line. Meaning of the symbols above the rows:

" || " means (when activated): if this item is found in a game, the game

       will be selected unless other conditions forbid;

" && " means (when activated): this item MUST be present in the game

       otherwise it will not be selected at all;

" != " means (when activated): this item is NOT allowed to be present.

Examples:

1. when "no score" is set on "&&" only the games without a result will be displayed.
2. when "no score" is set on "!=" all games that have a result will be shown whether it will be won, lost or drawn.

Secondly you'll have many items to be specified a bit more such as -white name-, -black name-, -free classification-, -notes-, -tournament- and -place-. You can give a text here that will be searched for in the database.
Other items like -date-, -Elo white-, -Elo black- and -Eco- can be specified in a range. For instance: Elo white =1600 ´2000 will make Rebel search for every game in which the white player has an ELO rating higher than 1599 but lower than 2001. When you set the "!=" block it will result in the selection of games of white players that has an ELO rating lower than 1600 or higher than 2000.

Thirdly you'll see four small boards corresponding with -moves (board 1)-, -position (board 2)-, -pattern (board 3)- and -material (board 4)- search items. What kind of position, pattern etc. the database will be searched for can be defined in the Start menu (see section Set up position for and Current game to). You can change the position to be searched for with the option of the Start menu, or also by clicking on the corresponding board. This also applies to pattern and material but not to moves. Keyboard users can use <CTRL>+<F2>, <CTRL>+<F3> and <CTRL>+<F4>,

Search on moves: the program will search for games containing the exact moves of the currently played game on the chessboard. This can be very useful for opening preparation.

Another 2 examples:

Example (1)

• -white player- defined as "Kasparov", set on "||";
• -black player- defined as "Karpov", set on "||";
• -date- defined =(left blank)-(left blank)-1998 ´(left blank)-(left blank) -1998, set on "&&";

will result in all games of the current database of the year 1998 in which Kasparov had white or Karpov had black

Example (2)

• -white player- defined as "Kasparov", set on "&&";
• -tournament- defined as "Linares", set on "&&";
• -date- defined =(left blank)-05-(left blank) ´(left blank)-06-(left blank), set on "!=";
• -black Elo- defined =2500 ´left blank, set on "!="
• -won by white- set on "!="

will result in all games of the current database which Kasparov played against players with an ELO-rating lower than 2500 in a Linares tournament in all months of the year except May and June and where he didn't win. This example is rather odd, especially for the month item, but it clearly shows that the possibilities are almost infinite.

5.2.2.2 DB: Search names

You can input either one or two names here, both of which will be searched for in the database. If you have typed just one name with white, the program will search for all the games by that player, starting with the games he or she played with white. If you type only one name with black, Rebel will start searching first for the games he or she played with black. If you have typed two names, the program will search for all the games played between those two players. This function works via the famous BTREE+ principle and will select games from a database of 1,000,000 games within seconds.

5.2.2.3 DB: Search ECO

You will be prompted to define the ECO range for which the database is to be searched. Because this option will make use of the index, searching via this option will probably be faster than via search mask.

5.2.2.4 DB: Search IX4

You will be prompted to define the text of the free index for which the Database is to be searched. Because this option will make use of the index, searching via this option will probably be faster than via search mask.

5.2.2.5 DB: Won by white

All games of the database that are won by white will be displayed.

5.2.2.6 DB: Draw

All games of the database that ended in a draw will be displayed.

5.2.2.7 DB: Won by black

All games of the database that are won by black will be displayed.

5.2.2.8 DB: No score

All games of the database that do not contain a score will be displayed.

5.2.2.9 DB: List by white name

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by white name.

5.2.2.10 DB: List by black name

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by black name.

5.2.2.11 DB: List by ECO

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by ECO code.

5.2.2.12 DB: List by free index

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by free index text.
