Amazon's CloudSearch is awesome, but it's query syntax is not for explaining to end-users. Enter luke-howard. This is a Scala library we wrote at Elemica to expose some of the advanced query functionality of CloudSearch to our users in a almost "search-engine-esque" syntax.
It exposes support for:
- Searching for multiple terms.
- Searching only against a specific field.
- Searching a specific field for one of a selection of values.
- Negative searches (or,
nots, per se). - Rudamentary support for numeric fields. (This will get better as we iterate.)
The project is named after the British Scientist Luke Howard who is responsible for the nomenclature that we commonly use for clouds. Much like Mr. Howard gave us some understandable terms to talk about the clouds in the sky, we hope this project will give end users some understandable means of asking questions of Amazon's CloudSearch.
Using luke-howard is a breeze. Simply import the QueryBuilder class from the
com.elemica.cloudsearch package and go to down.
import com.elemica.cloudsearch.QueryBuilder
QueryBuilder("bacon") // search for bacon
QueryBuilder("field:bacon") // search for bacon in the field named "field"
QueryBuilder("field:-123") // search for records where field doesn't match 123A complete set of examples can always be found in the QueryBuilderSpec.
