Method Details

getQueryLabel

public static String getQueryLabel(Collection<QueryStringTerm> termsUnique)

Parameters:

termsUnique - a list of QueryStringTerms

Returns:

a string that can be used to label a ES query

getFuzzyTermLabel

public static String getFuzzyTermLabel(AssociatedTerm correctedWord)

mapToBoolQueryBuilder

public static org.elasticsearch.index.query.BoolQueryBuilder mapToBoolQueryBuilder(org.elasticsearch.index.query.QueryBuilder query)

If the inserted query is a BoolQueryBuilder, the queryBuilder is just returned. If not, it is wrapped in a Boolean Query with the query at the MUST clause.

Parameters:

query - the query that should be wrapped into boolean query MUST-clause.

Returns:

a boolean query

mapToBoolQueryBuilder

public static org.elasticsearch.index.query.BoolQueryBuilder mapToBoolQueryBuilder(org.elasticsearch.index.query.QueryBuilder query,
 Function<org.elasticsearch.index.query.QueryBuilder,org.elasticsearch.index.query.BoolQueryBuilder> boolClauseFunction)

If the inserted query is a BoolQueryBuilder, the queryBuilder is just returned. If not, the provided function is called to wrap the query into a BoolQueryBuilder.

Parameters:

query - the query that should be wrapped into boolean query

boolClauseFunction - the wrapper function that is called in case the query is not a boolean-query.

Returns:

a boolean query

mergeQueries

public static org.elasticsearch.index.query.QueryBuilder mergeQueries(org.elasticsearch.index.query.QueryBuilder q1,
 org.elasticsearch.index.query.QueryBuilder q2)

Make sure both queries are combined as a boolean query with must-clauses. If one of them already is a boolean query with must clauses, the other one will be appended to it.

Parameters:

q1 - first query

q2 - second query

Returns:

q1 or q2 if one of them is null, otherwise a BoolQueryBuilder

validateSearchFields

public static Map<String,Float> validateSearchFields(Map<String,Float> weightedFields,
 FieldConfigAccess fieldConfig,
 Predicate<Field> additionalPredicate)

validateSearchField

public static Optional<SearchField> validateSearchField(String fieldName,
 FieldConfigAccess fieldConfig)
