If I put in the search term "なればなるほど" I get one result. If I use a subset of this term ("なればなる") I get zero results. Note the double quotes around the search term.
This leads me to think that there maybe information on the site that I'm unable to find because I haven't put in the precise term that the search engine likes.
Does anyone know what is going on here? I assume this is something to do with the concept (or lack of in Japanese) of word boundaries.
What is the best way to search to avoid problems like this?
