I can find exact word matching for queries in the experimental search API for Google App Engine. For example, the query "best hotel prices" would only match this exact phrase. It will not match texts such as "best hotel prices" or "hotels with best prices." Of course, it’s much more difficult to set the general text, but I thought that the search API, at least, could handle some of them.
Another example is the query “new cars”, which will not match the text “new and used cars”.
