Specified by:

execute in class QueryCommand

Parameters:

context - the query context containing search configuration

query - the Lucene query to convert (must be a FuzzyQuery)

boost - the boost factor to apply to the query

Returns:

OpenSearch QueryBuilder for fuzzy matching

Parameters:

context - the query context containing field mappings

fuzzyQuery - the Lucene FuzzyQuery to convert

boost - the boost factor to apply

Returns:

OpenSearch QueryBuilder configured for fuzzy matching
