[QUOTE="hwahrmann, post: 141355, member: 10391"] Well let me try to explain: You always specify an Operator and Restriction together. Operator: = < > =< => are fairly selfexplanatory. Selection Operator Restriction ---------------------------------------- genre.........=.............Pop <----- lists only Genres containing Pop genre.........like..........%Pop% <------lists Pop and Brit Pop. The "%" means any character artist..........like..........B% <-------lists only artists starting with B the <, >, =<, => operators make only sense on numeric restrictions. The Group was introduced to group similar data together, for speeding up the display. Selection Operator Restriction ---------------------------------------- artist........group........1 <-------groups all artists on the first char. so you have a list of "A", "B", "C", etc. artist On the next level you have artist only, which then lists all the artists with "A", when "A" was selected on screen of course. Selection Operator Restriction ---------------------------------------- artist........group........2 <-------groups all artists on the first 2 char. so you have a list of "AA", "AB", "AC", etc. This is only usefull on very large collections The Limit is there, if you want to restrict the number of items returned Selection Operator Restriction Limit -------------------------------------------------- title...............................................100 Lists only the first 100 titles found in your collections. I have no idea, wha someone would use this, but it's possible to do so. hope this helps. regards, Helmut [/QUOTE]
