advanced searches using extsearch plugin for BTN won't return results for certain strings

What steps will reproduce the problem?
1. Use extsearch to search BTN including a term like "S03E03" such as "Game of 
Thrones S03E03". Set category to anything but "all"
2.
3.

What is the expected output? What do you see instead?
Expect to see results.
No results.

What environment are you using?
1. My ruTorrent version is 3.5 SVN 2261
2. My rTorrent version is 0.9.2/0.13.2
3. apache, Debian Sid
4. Chrome, Mint 14

Are some errors present in the web-server log?
no

Are some errors present in the browser error console?
no

Please provide any additional information below.

When searching BTN using "all" the search string sent to BTN evaluates to 
https://broadcasthe.net/torrents.php?searchstr=game%20of%20thrones%20s03e03&arti
stname=game%20of%20thrones%20s03e03&action=basic&searchtags=&tags_type=0&order_b
y=s6&order_way=desc&page=1

This returns results.

When searching using any of the categories, "&action=basic" is replaced with 
"&action=advanced," eg "&action=advanced&filter_cat[1]=1", like so:

https://broadcasthe.net/torrents.php?searchstr=game%20of%20thrones%20s03e03&arti
stname=game%20of%20thrones%20s03e03&action=advanced&filter_cat[1]=1&searchtags=&
tags_type=0&order_by=s6&order_way=desc&page=1

This does not return results.

Not sure if this is a limitation of extsearch or not, but if it's something you 
can fix, that would be great.
