Exact query

The following field names are replaced with ${fieldname}, and the values are replaced with ${fieldvalue}

Digital

Single

QueryBuilder QB1 = Querybuilders.termquery ("${fieldname}", "${fieldvalue}");

Batch

QueryBuilder QB1 = Querybuilders.termsquery ("${fieldname}", "${fieldvalues}");

String

Single

QueryBuilder QB1 = querybuilders.termquery ("${fieldname}.keyword", "${fieldvalue}");

Batch

QueryBuilder QB1 = querybuilders.termsquery ("${fieldname}.keyword", "${fieldvalues}");

Fuzzy query numbers

Numeric queries are exact queries

String

QueryBuilder QB1 = querybuilders.morelikethisquery (New string[]{"${fieldname}"}, New string[]{"${fieldvalue}"}, NULL) ;

Range Query Numbers

Closed interval Query

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). from (${fieldvalue1}). to (${fieldvalue2});

Open interval Query

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). from (${fieldvalue1}, False). to (${fieldvalue2}, False);

Greater than

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). GT (${fieldvalue});

Greater than or equal

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). GTE (${fieldvalue});

Less than

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). LT (${fieldvalue});

Less than or equal

QueryBuilder QB1 = Querybuilders.rangequery ("${fieldname}"). LTE (${fieldvalue});

Multi-Criteria Query

QueryBuilder QB1 = querybuilders.morelikethisquery (New string[]{"${fieldname1}"}, New string[]{"${fieldvalue1}"}, NULL); QueryBuilder QB2 = Querybuilders.rangequery ("${fieldname2}"). GT ("${fieldvalue2}"); QueryBuilder Qb3 = Querybuilders.boolquery (). Must (QB1). must (QB2);
