At the advice of my son, I've purchased an iMac (Mac OS X, Version 10.5.4, 2.4 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM), and I like it despite the steep learning curve. If I were using a Windoze os, I'd be able to clear the cache for computer file searches, and the History would be cleared without losing the files that were searched for. I'm trying to learn how to do the same (i.e., clear the cache of searched files) for searches I've done on my iMac I open finder and on the left side of the window, I see the headings: "DEVICES" (with xx's iMac, Macintosh HD, and iDisk listed below the heading), "PLACES" (with Desktop, Applications, Documents, and bp listed below the heading), and "SEARCH FOR" (with Today, Yesterday, Past Week, All Images, All Movies, All Documents under the heading). I know that this area on the left side of Finder window is referred to as the "Sidebar". When I click on Today, Yesterday, Past Week, All Images, All Movies, All Documents, I see hundreds of documents from numerous searches. What I want to do is clear the contents of each of the categories, so that I can start searches with less clutter, etc. How do I clear the search results (i.e., the listed files, images, movies and/or documents) from each of the categories listed under the "SEARCH FOR" heading? Just to be clear, I want to be able to click on the Today, Yesterday, Past Week, All Images, All Movies, All Documents categories under "SEARCH FOR" heading and have absolutely no files show up. Also to be clear, I've searched this site for an answer to this question, but the response was not an answer. The response was merely the suggestion that the categories be removed from the Sidebar area, reprinted here: "Ah, alright...watch out! These are not history items. These are Smart Folders showing actual content of your hard drive, used Today, Yesterday and so on. DON'T delete them or you will run into serious trouble. To remove the Smart Folders from the sidebar, just drag them off the sidebar and they will vanish in a puff of smoke. /Rupert" I've found that removing the categories does not clear them of the search histories. I can remove them, and then put them back on, but the same hundreds of files are also put back on. The problem with Rupert's suggestion is that I don't want to get rid of the categories, I want to get rid of the contents of the categories. Sorry about the long-winded question, but it's better to throw out information you don't need than to wonder about information you don't have.
