If you quote the search terms, it only looks for an exact match. (The search 
page notes this.) You can quote single words.

If you don't quote the search terms, it looks for forms of the word.

Quoted text of multiple words is far more expensive to search for (as the 
matching documents need to be checked to see if the words appear together) 
than unquoted text. Searching for forms would just be too much (it barely 
finishes in 15 seconds as it is on the wide search).

Also, when I search for "expression function" (in quotes), AI-177 is the 
third match. Not sure why you didn't see it (the index hasn't changed 
recently), so I should have gotten the same results that you did. Also note 
that the most recent versions of AI-177 probably aren't in the search index 
at all.

If I search for "expression function" without the quotes, AI-177 is also the 
third match.
