I meant searching games played by a specific player here on Chess.Com that belong to a specific opening ... Not using chessbase or anything like that. Basically I want to search chess.com's database that is if such a thing exists. Thanks in advance.
games from a specific position

You use the Explorer here and you can choose to look at the games of any player here on Chess.com, in any opening.
In your list, it appears that you haven't played many games, and you lost to a 1 g4 and 1 Nc3 openings.
I checked and see that you only played a total of 91 games here. Other players may have a lot more games in their archive available.

You wanted to know games by ECO number. They dropped the ECO codes in V3. However, they only went through 4 moves in V2.
However, they still label the variations. You need to have enough games to get down into the variations. In your case, it appears that you like to play the modern variation of the accelerated dragon variation of the Sicilian.
And the archive offers 3 games of yours in the variation seen above- two draws and a loss.

Thanks to all. It helped me look into specific games of a specific player very easily as well as I could download in pgn file format all the games. The explorer option is the best way to go about it. Again Thanks much. Pfalcon1949

Ok. Here is a problem with using explorer approach (by the way the other approach suggested does not work at all). Once you searched a position say it shows up like 200 games. You click on the number and it shows the list of the games. However, it only lists the first 50 games and you can download them all by a single click. A really nice feature indeed. But how to get the remaining 150 games? Not clear and I could not figure it out. Please help if you do know. Thanks in advance.
I would like to search and find all games say in ECO code xx.... and player name yy. How do I achieve that?
