I wish this helpful for you Are you sure Scrapy sees the web page in the same way as you? Nowadays, more and more sites are built by Javascript, Ajax .. And those dynamic content might need a fully functional browser to be fully populated. However, neither Nutch nor Scrapy will handle those out of box.
First of all, you need to make sure the web content you are interested in can be retrieved by scrapy. There are a few ways to do it. I usually use urllib2 and beautifulsoup4 to give it a quick try. And the your start page failed my test.
$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib2
>>> from bs4 import BeautifulSoup
>>> url = "https://www.ghcjobs.apply2jobs.com/ProfExt/index.cfm?fuseaction=mExternal.returnToResults&CurrentPage=1"

>>> html = urllib2.urlopen(url).read()
>>> soup = BeautifulSoup(html)
>>> table = soup.find('div', {'id':'VESearchResults'})
>>> table.text
u'\n\n\n\r\n\t\t\tJob Title\xa0\r\n\t\t\t\r\n\t\t\n\r\n\t\t\tArea of Interest\xa0\r\n\t\t\t\r\n\t\t\n\r\n\t\t\tLocation\xa0\r\n\t\t\t\r\n\t\t\n\r\n\t\t\tState\xa0\r\n\t\t\t\r\n\t\t\n\r\n\t\t\tCity\xa0\r\n\t\t\t\r\n\t\t\n\n\n\r\n\t\t\t\t\tNo results matching your criteria.\r\n\t\t\t\t\n\n\n'

How to pass multiple arguments to Scrapy spider (getting error running 'scrapy crawl' with more than one spider is no lo

With these it helps No scrapy problem, I guess. It's how your shell interprets input, spliting tokens in spaces. So, you must not have any of them between the key and its value. Try with:
scrapy crawl dmoz -a address="40-18 48th st" -a borough="4"

it helps some times You have to add a .py extension to your dmoz_spider file. The file name should be dmoz_spider.py.

(Python, Scrapy) Taking data from txt file into Scrapy spider

will be helpful for those in need You can override the start_urls logic in spider's start_requests() method:
class Myspider(scrapy.Spider):
    name = 'myspider'

    def start_requests(self):
        # read file data
        with open('filename', 'r') as f: 
            start, end = f.read().split('\n', 1)
        # make range and urls with your numbers
        range_ = (int(start.strip()), int(end.strip()))
        start_urls = ["https://domain.com/%d" % i for i in range(range_)]
        for url in start_urls:
            yield scrapy.Request(url)
def start_requests(self):
    for url in self.start_urls:
        yield scrapy.Request(url)

Scrapy runs all spiders at once. I want to only run one spider at a time. Scrapy crawl <spider>

wish of those help You can run scrapy from your script (https://scrapy.readthedocs.io/en/latest/topics/practices.html#run-from-script), for example:
import scrapy
from scrapy.crawler import CrawlerProcess

class YourSpider(scrapy.Spider):
    # Your spider definition


process = CrawlerProcess()
process.crawl(YourSpider)
process.start()
