### Question:
SolrManager extends BaseSearchManager implements Initializable { @Override public void index(List<Component> components) { SolrClient solrService = getServer(); Map<String, List<ComponentAttribute>> attributeMap = new HashMap<>(); Map<String, List<ComponentTag>> tagMap = new HashMap<>(); if (components.size() > 1) { ComponentAttribute componentAttributeExample = new ComponentAttribute(); componentAttributeExample.setActiveStatus(ComponentAttribute.ACTIVE_STATUS); List<ComponentAttribute> allAttributes = service.getPersistenceService().queryByExample(componentAttributeExample); attributeMap = allAttributes.stream().collect(Collectors.groupingBy(ComponentAttribute::getComponentId)); ComponentTag componentTagExample = new ComponentTag(); componentTagExample.setActiveStatus(ComponentTag.ACTIVE_STATUS); List<ComponentTag> allTags = service.getPersistenceService().queryByExample(componentTagExample); tagMap = allTags.stream().collect(Collectors.groupingBy(ComponentTag::getComponentId)); } List<SolrComponentModel> solrDocs = new ArrayList<>(); for (Component component : components) { SolrComponentModel solrDocModel = new SolrComponentModel(); solrDocModel.setIsComponent(Boolean.TRUE); solrDocModel.setId(component.getComponentId()); solrDocModel.setNameString(component.getName()); solrDocModel.setComponentType(component.getComponentType()); solrDocModel.setDataSource(component.getDataSource()); solrDocModel.setDataSensitivity(component.getDataSensitivity()); solrDocModel.setName(component.getName()); String description = StringProcessor.stripHtml(component.getDescription()); solrDocModel.setDescription(description.replace("<>", "").replace("\n", "")); solrDocModel.setUpdateDts(component.getUpdateDts()); solrDocModel.setOrganization(component.getOrganization()); List<ComponentTag> tags; List<ComponentAttribute> attributes; if (components.size() > 1) { tags = tagMap.get(component.getComponentId()); if (tags == null) { tags = new ArrayList<>(); } attributes = attributeMap.get(component.getComponentId()); if (attributes == null) { attributes = new ArrayList<>(); } } else { tags = service.getComponentService().getBaseComponent(ComponentTag.class, component.getComponentId()); attributes = service.getComponentService().getBaseComponent(ComponentAttribute.class, component.getComponentId()); } StringBuilder tagList = new StringBuilder(); StringBuilder attributeList = new StringBuilder(); for (ComponentTag tag : tags) { tagList.append(tag.getText()).append(" "); } for (ComponentAttribute attribute : attributes) { ComponentAttributePk pk = attribute.getComponentAttributePk(); attributeList.append(attributesToString(pk.getAttributeType(), pk.getAttributeCode())); } solrDocModel.setTags(tagList.toString()); solrDocModel.setAttributes(attributeList.toString()); solrDocModel.setArticleHtml(""); solrDocs.add(solrDocModel); } if (solrDocs.isEmpty() == false) { try { solrService.addBeans(solrDocs); solrService.commit(); } catch (IOException | SolrServerException ex) { throw new OpenStorefrontRuntimeException("Failed Adding Component", ex); } } } protected  SolrManager(PropertiesManager propManager, SolrClient client); static SolrManager getInstance(); static SolrManager getInstance(PropertiesManager propertiesManager, SolrClient client); void init(); void cleanup(); SolrClient getServer(); @Override void initialize(); @Override void shutdown(); @Override boolean isStarted(); @Override ComponentSearchWrapper search(SearchQuery searchQuery, FilterQueryParams filter); @Override void index(List<Component> components); @Override IndexSearchResult doIndexSearch(String query, FilterQueryParams filter); @Override IndexSearchResult doIndexSearch(String query, FilterQueryParams filter, String[] addtionalFieldsToReturn); @Override List<SearchSuggestion> searchSuggestions(String query, int maxResult, String componentType); @Override void deleteById(String id); @Override void deleteAll(); @Override void saveAll(); @Override void resetIndexer(); static final String SOLR_ALL_QUERY; static final String SOLR_QUERY_SEPERATOR; }### Answer:
