changes have been made in recent months. For one thing, if your search had looked for "chips," the old system would find listings that had "chips" in the title (or description if you added that feature). Now it includes items that might not have "chips" in the title, but it has "chips" in the category. At least I noticed this with Matchbox cars - Hot Wheels cars erroneously listed in the Matchbox classification are now included in my search results.
