本文主要是介绍Integrate with Portal Search，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Registering Entries with the Search Framework

创建EntrySearchRegistrar.java
1.实现activate(BundleContext bundleContext)和deactivate()

    @Activateprotected void activate(BundleContext bundleContext) {_serviceRegistration = modelSearchRegistrarHelper.register(Entry.class, bundleContext, modelSearchDefinition -> {modelSearchDefinition.setDefaultSelectedFieldNames(Field.COMPANY_ID, Field.ENTRY_CLASS_NAME,Field.ENTRY_CLASS_PK, Field.UID, Field.SCOPE_GROUP_ID, Field.GROUP_ID);modelSearchDefinition.setDefaultSelectedLocalizedFieldNames(Field.TITLE, Field.CONTENT);modelSearchDefinition.setModelIndexWriteContributor(modelIndexWriterContributor);modelSearchDefinition.setModelSummaryContributor(modelSummaryContributor);modelSearchDefinition.setSelectAllLocales(true);});}@Deactivateprotected void deactivate() {_serviceRegistration.unregister();}

设置用于从搜索引擎检索结果文档的默认选定字段名称

2.创建引用

	@Reference(target = "(indexer.class.name=com.liferay.docs.guestbook.model.Entry)")protected ModelIndexerWriterContributor<Entry> modelIndexWriterContributor;@Referenceprotected ModelSearchRegistrarHelper modelSearchRegistrarHelper;@Reference(target = "(indexer.class.name=com.liferay.docs.guestbook.model.Entry)")protected ModelSummaryContributor modelSummaryContributor;private ServiceRegistration<?> _serviceRegistration;}

Indexing Entries

1.Implementing ModelDocumentContributor

2.Implementing ModelIndexerWriterContributor

检索所有entries并将其添加到集合中

3.Implementing EntryBatchReindexer

Querying for Entry Documents

1.实现EntryKeywordQueryContributor ，为正在进行的搜索查询提供子句。

@Overridepublic void contribute(String keywords, BooleanQuery booleanQuery,KeywordQueryContributorHelper keywordQueryContributorHelper) {SearchContext searchContext =keywordQueryContributorHelper.getSearchContext();queryHelper.addSearchLocalizedTerm(booleanQuery, searchContext, Field.TITLE, false);queryHelper.addSearchLocalizedTerm(booleanQuery, searchContext, Field.CONTENT, false);queryHelper.addSearchLocalizedTerm(booleanQuery, searchContext, "entryEmail", false);}
