I'm trying to pull down search query information, but my API call doesn't bring down the queries with 0 conversions that i see on the web version.
Here's my AWQL call:
("SELECT Query, Conversions "
"FROM SEARCH_QUERY_PERFORMANCE_REPORT "
"DURING YESTERDAY")
Which results in a list of 90 terms, all with a conversion greater than 0.
When I go on the web dashboard and do the same thing...

I see 16k search terms, and tons of them with no conversions. Why?
