Use cases

Geodistance search

751 cities are indexed, then perform a search to find cities far by 1000 km from Paris. Search results are showed in reversed order (the farthest displayed first).

The list of cities is stored in src/test/resources/cities.txt

Search parameters can be changed, using the following constants:

NB_MAX_RESULTS (default : 200)

ORIGIN_CITY_LON (default : 2.34 - Paris longitude)

ORIGIN_CITY_LAT (default : 48.86 - Paris lattitude)

DISTANCE_FROM_ORIGIN (default : 1000)

DISTANCE_UNIT (default : DistanceUnit.KILOMETERS)

Scan Search

728 ebooks are indexed, then perform a scan search for ebooks where the word "Biological" is part of their name. The list of ebooks is stored in src/test/resources/ebook2013.csv

Search parameters can be changed, using the following constants:

SCROLL_SIZE (default : 5) - retrieve 5 items per request

TEXT_TO_SEARCH (default : "Biological")
