Presearch is an alternative search engine (similar to Google) that allows you to search a range of websites and social media accounts. Besides, it pays you per search you conduct on it, using its own ERC-20 type coin named "PRE coins". These PRE coins can then be swapped for KUcoin and traded.
The good thing about presearch is you can set it up to search academic search engines. I have customised its interface to search pubmed, Google Scholar, and a university library interface, so that now all my searches are integrated through the presearch. Here is the step by step process:
Step 1: Visit the presearch interface and click on the "cog wheel"
Step 2: Click on "Add New Provider"
Step 3: Click on the tab named "Add New Provider" and fill in the form fields for "Name:" and "URL:". The "Name" field is a descriptive name you can give to your search provider (for example, "Google Scholar"), and the "URL:" is the search URL field.
For example, if you search Semantic Scholar with a search term, copy the search inteface URL, so it will be something like:
https://www.semanticscholar.org/search?q=
Copy and paste this to the "URL:" form field, and then select an icon.
