Liferay搜索按AssetTags和关键字搜索文本

Question

我正在尝试通过AssetEntries实现自定义搜索portlet.目前AssetEntryQuery不允许使用关键字进行搜索.我正在尝试搜索FacetedSearcher.按关键字搜索似乎没问题.但是当我试图通过AssetTagNames进行搜索时

searchContext.setAssetTagNames(assetTagNames)

它根本不起作用.这是我的一段代码

 SearchContext searchContext = new SearchContext();
         Facet assetEntriesFacet = new AssetEntriesFacet(searchContext);
         assetEntriesFacet.setStatic(true);
         searchContext.addFacet(assetEntriesFacet);

         /*MultiValueFacet multiValueFacet=new MultiValueFacet(searchContext);
         multiValueFacet.setFieldName("assetTagNames");
         multiValueFacet.setStatic(false);
         searchContext.addFacet(multiValueFacet);*/

       searchContext.setCompanyId(themeDisplay.getCompanyId());
       String []assetTagNames=new String[1];
        assetTagNames[0]=  assetTagName;
        searchContext.setAssetTagNames(assetTagNames);
        searchContext.setKeywords(keywords);
        String[] entryClassName = {JournalArticle.class.getName()};
        searchContext.setEntryClassNames(entryClassName);

        Indexer indexer = FacetedSearcher.getInstance();
       // searchContext.setAndSearch(true);
        Hits hits = indexer.search(searchContext);
        System.out.println("Hits: " + hits.getLength());

请求searchKeyword的结果查询:key1key1 assetTagName:sometag

+(+(companyId:1) +((+(entryClassName:com.liferay.portlet.journal.model.JournalArticle) +(status:0)))) +(assetCategoryTitles:*key1key1* assetCategoryTitles_en_US:*key1key1* assetTagNames:*key1key1* comments:key1key1 content:key1key1 description:key1key1 properties:key1key1 title:key1key1 url:key1key1 userName:*key1key1* classPK:key1key1 content_en_US:key1key1 description_en_US:key1key1 entryClassPK:key1key1 title_en_US:key1key1 type:key1key1)

如您所见,AssetTag未应用于查询.我已经尝试过了

searchContext.setAttribute("assetTagNames",assetTagName);

并评论了MultiValueFacet代码,但没有结果.为了进一步我需要搜索dateRange和类别.有人有什么想法吗？

幸运的是解决了这个.

如果您想搜索标签,您可以使用单独的方面,例如

        MultiValueFacet assetTagsFacet = new MultiValueFacet(searchContext);
        assetTagsFacet.setFieldName(Field.ASSET_TAG_NAMES);
        searchContext.addFacet(assetTagsFacet);

也可以searchContext.setAttribute("assetTagNames", assetTagName);代替使用searchContext.setAssetTagNames(assetTagName);

通过类别搜索同样的事情:

        MultiValueFacet assetCategoriesFacet = new MultiValueFacet(searchContext);
        assetCategoriesFacet.setFieldName("assetCategoryTitles");
        searchContext.addFacet(assetCategoriesFacet);
        searchContext.setAttribute("assetCategoryTitles", assetCategoryName);

另外我想通过自定义类型的JournalArticle进行搜索,我为此创建了facet,但在查询中得到了"type"两次.作为解决方案,我在设置entryClassName期间使用了MultiValueFacet而不是AssetEntriesFacet

    MultiValueFacet assetEntriesFacet = new MultiValueFacet(searchContext);
    assetEntriesFacet.setFieldName("entryClassName");
    searchContext.setAttribute("entryClassName",JournalArticle.class.getName());
    searchContext.addFacet(assetEntriesFacet);
