Using Field Names, you are able to define specific fields within which you wish to search.
For example, if you are searching for someone called George. Your search term would
look like name:George
Using a * symbol, you are able to search for partial words. For example, if you're unsure whether a document is named policy or policies, you could use the search term Polic*
You don't have to search for exact word matches. Using the symbol ~ you can search for the approximation of a word. For example, using the previous policy example using fuzziness you would search for polciy~
