Once you have combined the various components into a definitive search query, you can restrict your search results by, for instance, language, type of study, year, etc. Use the following tools for this:
Search strategies designed by other institutes/research groups to serve as a search filter.

Watch the PubMed Tutorial for more information.
You can find Clinical Queries in the Advanced Search Builder via the More Resources tab in the top left.

Go here to see what exactly PubMed searches for.
The Systematic Reviews filter option on the Clinical Queries page is identical to the option under Article types in the Filter Sidebar.
Some of the filter options are simply MeSH terms, such as the filter option Humans. In this particular case, you actually expand your query with AND Humans[MeSH], indicating that all articles should contain the MeSH term Humans. This action instantly rejects articles without MeSH (found through [tiab] searches).
Want to make sure that a filter is not a MeSH term? Check the PubMed status of your articles before and after activating the filter. You can find the PubMed status in the Abstract format.
In addition to the PubMed search filters, you can use search filters designed by other institutes/research groups, or you can make one yourself.
