When perfoming a systematic review (SR) search your search strategy is broad (high sensitivity). Results vary between 2000-8000 references and only about 5% will be useful for your research question. If you do not have around 1 – 2 years for an SR, there are other options, like e.g. a Rapid review or a Review of Literature.
The Cochrane Handbook recommends searching in Embase (if possible), Medline and Cochrane CENTRAL. Bramer 2017 adds Web of Science and Google Scholar to the list.

*Due to licensing and copyright law I am not allowed to have a subscription to the different databases (except PubMed) and sell the references. There are 3 work arounds:

1. A temporary log in to your institute to access the database(s), or

2. During the online appointment we choose the relevant index and title/abstract terms. You copy and paste these into a Word document, which you send to me. I will translate it into the different search syntaxes. You then copy and paste the search into the database and send the results to me. I will deduplicate the references for you and then send the results including the Word document back to you.

3. I travel to the nearest institute which has access to the database(s). This adds at least 2 hours. Maybe more, if there are changes to the search string afterwards.
