Welcome to the forums :)
According to our Head of Technology, the SRL's 10 searches per day limit is due to the fact that our data provider has placed a limit on how many we can do per day, so to be fair to the users we have had to pass this limit down to them.
However, in the next couple of months we are going to work with our data provider to change and increase this limit.
If your search results return with dashes "-" it may be that the global search limit has been reached for that keyword. If it returns with a "0" it means the lab found no results.
Kindly try waiting for at least 24 hours before doing another search and let us know how you get on.
Talk to you soon!
