Organic links do not contain individual job postings.

Indeed.com - http://www.indeed.com
https://ads.indeed.com/jobroll/xmlfeed

**Why did you choose this data source?**
Indeed is the number 1 Job Search site in the US
http://blog.indeed.com/2013/02/14/independent-study-indeed-1-external-source-of-hire/

**Are there any other alternative (better) data sources?**
Alternatives:
* GitHub Jobs

Users looking for a job

https://dukgo.com/ideas/idea/758/jobs-search-via-indeed-com

**Which existing instant answers will this one supersede/overlap with?**
GithubJobs.pm
The current implementation uses the same triggers and regular expression from GithubJobs.pm

The GitHub Jobs api could be modified to only look for programming specific jobs using keywords like "perl, java, javascript, C#, programming, etc".

**Are you having any problems? Do you need our help with anything?**

I could not figure out why GitHub Jobs superseded the IndeedJobs instant answer when both triggered results.

**Required environment variable**
* *DDG_SPICE_INDEED_JOBS_PUBLISHER* - should contain the publisher number for Indeed's Api. You can register via https://ads.indeed.com/jobroll/xmlfeed
