The search terms box is a word search - so whatever you enter is what is searched for in the title, author, and for recipes in the ingredients. It's not that it is "pernickety" but that is the way that searches work. So if you search for Rachel Ray you will get zero results as her name is spelled Rachael Ray. As soon as you add the "t" to Aus there is no longer a match with Delicious (Aus).
For ingredients we have entered variables into the database so if you type a word one way it will also find the other e.g. typing lasagne or lasagna will show the same results. But we don't have variable names options for magazines so it does have to be a precise match.
The filters on the right are a precise match to the database entry so no typing is required. There is also a list of all magazines we index under Popular searches. Click on Delicious (Aus) there and you get the complete list of issues.
