Any EBSCO database (ie. PsychoInfo & CINHAL) will not allow for multiple keywords to be searched at the same time.
PS. I was able to search for more than 2 terms last week, but the "server dropped the connection" message began recently.
Thank you for reporting this problem! We have no idea what's wrong but we will report it to EBSCO.
In the meantime, you can work around this by using the Search History feature. Here's how to use it:
1. Search your terms one at a time. EBSCO seems to be OK if you search a phrase, so you don't need to search one word at a time.
2. When you have searched each of your terms, delete your last search from the search box and then open the search history. Look for Search History just below the search boxes.
4. The search history will show the sets you have created. Choose the sets you want to combine by putting checkmarks in front of them and then use the buttons at the top of the search history to combine them with AND or OR. If you need to use both AND and OR in your search, combine the sets with OR first and then go back and use AND.
Let me know if you need any help in doing this. I'm sorry that EBSCO is not working right. I'll let you know when I hear they've fixed the problem.
