search_index()

errorT search_index	(	const scidBaseT *	base,
		HFilter &	filter,
		int	argc,
		const char **	argv,
		const Progress &	progress
	)

search_index() - search for games using game's IndexEntry info

Parameters

base	the scidBaseT to search
filter	the filter to be modified with the result of the search (RESET, AND, OR operations can be applied to the filter)
argc	number of argv elements
argv	an array of string pairs <criteria,value>
progress	report search progress to UI

This function perform a fast games search using the IndexEntry info. Criteria should start with the char '-' and can include the optional trailing chars '!': meaning that we want the games that do not match the <criteria,value> pair '|': that allows to search for games that match at least one <criteria,value> in a group of <criteria,value> pairs

Names searches (-player, -white, -black, -event, -site -round) have special rules:

• normal searches ignore case and spaces, so -player carlsen is equal to -player C a R L s en
• player surname and name are usually separated by the char ,
• exact searches (that do not ignore case and spaces) can be performed enclosing the searched value in "" like -player "Carlsen, Magnus"

Examples: -player "Carlsen, Magnus" means search for games played by (either as white or black) Carlsen (surname) Magnus (name)

-player carlsen -black kramnik means (white name contains 'carlsen' || black name contains 'carlsen') && (black name contains 'kramnik')

-white carlsen -black anand -black| kramnik -black| aronian means (white == carlsen) && (black == anand || black == kramnik || black == aronian) and will find the games played by carlsen as white against anand, or kramnik, or aronian

-elo "2700 4000" -event! blitz means elo > 2700 && elo < 4000 && event != blitz and will find the games played by players with elo greater or equal than 2700, excluding the blitz events

-welo "2700 4000" -belo|! "0 2700" -delo "-200 200" means (white elo > 2700 && white elo < 4000) || (belo is not in the range 0-2700) && ((welo - belo) > -200 && (welo - belo) < 200)
