You can use the search operators AND, OR and NOT to combine search terms and concepts. These are the most commonly known and used operators.
The operators AND and NOT limit the number of results from a search. The operator OR does the opposite; it increases the number of results.
To see how this works, take a look at The Boolean machine. Move your cursor over the operators AND, OR and NOT to see how they determine your search.
You can also combine more than two search terms. Use brackets to indicate the priority. For example (Money OR inflation) AND banking.

When documenting a search strategy it is recommended that a personal account be created in any databases to be searched. The personal account signup option is usually on the upper right. Saved search histories of final searches can then be downloaded from the databases
This is an example of a documented search strategy on Prospero for a rapid review
It is also recommended that a PRISMA flow diagram of the entire search strategy be included. The PRISMA Flow Diagram Generator is an Open Source online tool that may assist you in producing your PRISMA flow diagram.
Search Filters – sit on top on your subject searches Carry out your subject searches first, evaluate and make sure you are happy with the relevancy of the results. Then apply the filter.
