I get that for general-purpose searches this is a good idea, but it would be nice if there was an easy way to disable this when you know you don't want it - for example, for most programming searches, if I type SomeAPINameHere the most relevant results will always be those that include my search term verbatim. I don't need Google to helpfully suggest "Did you mean Some API Name Here?", which will virtually always return lower-quality search results.
Early Google was a breath of fresh air compared to the stemming that its competitors at the time did, but nowadays even putting search terms in quotes doesn't seem to return the same quality of results for these types of queries that Google used to have.
