On your keyboard 1 space works as an AND. It links words/phrases or search functions entered with an AND. e.g. Manager Java Oracle finance :will search for an exact match of manager AND java AND oracle AND finance
To cater for an AND/OR function. Place a pipe or | in between 2 different words. e.g. bcom* | "bachelor of commerce" :will match bcom, bcomm, bcompt and/or bachelor of commerce, etc. The pipe function is achieved using the SHIFT + (Back Slash) keys on your keyboard.
Placing a phrase in between inverted commas/quotation marks, ("PHRASE") will match the full phrase exactly. e.g. "business analyst" :will search for an exact match of the full phrase businessspaceanalyst
A phrase is defined as more than one word that you would like the system to match together as one: e.g. "human resources" or "personal assistant" or "sales executive" or "project manager", etc.
Place an asterisk or * at the end of an incomplete word for a wildcard match. e.g. financ* :will match all words starting with financ and ending in any other way, e.g. finance, financed, finances, financing, financial, etc.
