You can combine eBay search terms with brackets and commas, and set terms to be ignored with hyphen/minus signs:

(kilt,kilts) wool -(ties,jacket,hose,skirt,sporran,hat,socks,scarf,ju mper,women,womens,womans,ladies,flashes,tie,boys,a crylic)

Here I am looking for auctions with titles that include the words KILT or KILTS, they have to have WOOL in the title, and I want to ignore auctions that have all those other terms in the title.

Paste that in and see how it works for you. Then edit for desired results. ("Include description" will open another can of worms.)
