The query string.

originalQueryString

private java.lang.String originalQueryString

the original query String before normalization

analyzedQuestion

private AnalyzedQuestion analyzedQuestion

The analyzed question.

score

The score of the query. More specific queries receive a higher score than simple keyword queries. The score is used by the answer selection module to score the results retrieved with this query.

extractionTechniques

private java.lang.String[] extractionTechniques

The answer extraction techniques applied to results retrieved with this query.

qi

private QuestionInterpretation qi

The interpretation of the question used to generate this query (optional).
