[問題] 又是關鍵字的問題...
是的很抱歉，不才的我又要尋求大家的幫助了
在檢索技巧仍無法有效提升但是又遲遲做不出檢索結果的情況下
想請問大家關於以下產品的us關鍵字選擇，因為我目前連ipc都選不出來啊~~~
http://www.securitycameradistributor.com/product_p/jv35.htm
目前使用的關鍵字是
camera and (tester or installation)
monitor OR monitored OR surveillant OR surveillance
通常先放在spec再放abst，但是我檢索結果還是找不到 =ㄦ=
請問大家是否有更好檢索字串，謝謝大家了!
