Examples of org.apache.lucene.index.IndexableField

org.apache.lucene.index.IndexableField
Represents a single field for indexing. IndexWriter consumes Iterable<IndexableField> as a document. @lucene.experimental

                    // if we have already seen this GeoName and we are removing duplicates, skip to the next doc
                    continue;
                }
                String matchedName = INDEX_NAME.getValue(doc);
                if (!geoname.isAncestryResolved()) {
                    IndexableField parentIdField = doc.getField(IndexField.PARENT_ID.key());
                    Integer parentId = parentIdField != null && parentIdField.numericValue() != null ?
                            parentIdField.numericValue().intValue() : null;
                    if (parentId != null) {
                        Set<GeoName> geos = parentMap.get(parentId);

                            geos = new HashSet<GeoName>();
