I hope this question is appropriate for this exchange (I think it is too specific for meta?).
We are looking for a search engine that is capable of performing a search of all available biological/medical/epidemiological scientific literature (So more on the scope of Google than Elsevier or similar subscription services) and providing as many as possible of the following features:
- Keyword search
- Range of dates
- Boolean terms (AND NOT etc.)
- Option to download and sort
- Email alerts.
Does anyone know of a search engine or service that has these capabilities? (A paid subscription is fine).
Thank you in advance for your patience.
