[twitter-dev] What is included In the "Queries are limited 140 URL encoded characters." restriction?

[leonspencer]

What us being counted as part of the length of the query - entire
query string? What names (of query string name/value pair), values
(of query string name/value pair), and delimiters are counted in the
Twitter API restriction "Queries are limited 140 URL encoded
characters?" I've run the Twitter API Advanced Search Form to generate
queries:

http://search.twitter.com/advanced

At some point it will say the query is too large - should be 140 but
is 155

Query example:
http://search.twitter.com/search?q=&ands=All+of+these+words&phrase=This+exact+phrase&ors=Any+of+these+words&nots=None+of+these+words&tag=Balloonboy&lang=en&from=leonspencer&to=&ref=&near=&within=15&units=mi&since=2009-10-15&until=2009-10-16&rpp=15

What us being included in this length? The entire query string? (i.e. ?
q to the end or just the length of the values?

Thank you
