org.apache.stanbol.entityhub.yard.solr.model.IndexField
Represents a logical field within the index.
A logical field consists of the following parts:
- The path, a list of path elements (URIs parsed as String)
- The {@link IndexDataType}
- The language
Logical fields are than mapped with an 1..n mapping to actual fields in the Index Documents. This functionality is provided by the {@link FieldMapper} @author Rupert Westenthaler

                    List<String> indexFields = new ArrayList<String>();
                    for(String field : fields){
                        //we need to get the actual fields in the index for the
                        //logical fields parsed with the constraint
                        IndexDataTypeEnum mapedIndexTypeEnum = IndexDataTypeEnum.forDataTyoe(simConstraint.getContextType());
                        IndexField indexField = new IndexField(Collections.singletonList(field), 
                            mapedIndexTypeEnum == null ? null : mapedIndexTypeEnum.getIndexType(),
                            simConstraint.getLanguages());
                        indexFields.addAll(fieldMapper.getQueryFieldNames(indexField));
                    }
