====

For all the operators, leave limit and offset empty

1. create KeywordSource with properties:
   keyword: zika
   data source: promed
   matching type: conjunction (default)
   attribute: content

2. create Projection
   attributes: _id, webpage, content

3. connect KeywordSource with Projection

4. create Regex_Person
   regex:
   (A|a|(an)|(An)) .{1,40} ((woman)|(man))
   attribute: content

5. connect Projection with Regex_Person

6. create NLP_Location
   type: location
   attribute: content

7. connect Projection with NLP_Location

8. create Regex_Date
   regex:
   (((0?[1-9])|(1[0-2]))(\s|-|.|/)((0?[1-9])|([12][0-9])|(3[01]))(\s|-|.|/)([0-9]{4}|[0-9]{2}))|((0?[1-9])|([12][0-9])|(3[01])) ((jan(uary)?)|(feb(ruary)?)|(mar(ch)?)|(apr(il)?)|(may)|(june?)|(july?)|(aug(ust)?)|(sep(tember)?)|(oct(ober)?)|(nov(ember)?)|(dec(ember)?))
   attribute: content

9. connect Projection with Regex_Date

10. create Join1
    Join attribute: content
    id attribute: _id (default)
    PredicateType: CharacterDistance (default)
    distance: 100

11. connect Regex_Person and NLP_Location with Join1

12. create Join2
    (same properties as Join1)

13. Connect Join1 and Regex_Date with Join2

14. Create TupleStreamSink (view results)

15. connect Join2 with TupleStreamSinkFor all the operators, leave limit and offset empty
