Faceted Searching in 6.1

[Jonathan Lloyd，修改在12 年前。]

Hello,

I am trying to create a basic faceted search using the 6.1 search API, but have been running into some issues. I'm fairly new to using Liferay and there doesn't seem to be any real documentation on how to do this. I basically want the user to search based on a keyword, category, subcategory, and added date range. I've looked over Ray Auge's blog post and I'm still confused as to what does what.

It seems that whenever I provide a keyword to the SearchContext object that always overrides whatever categoryIds I set using searchContext.setCategoryIds(new long[]{ 11702 }). Also, when trying to use the JSON facet configuration to search a category it seems to have no effect at all. Does setting values in the SearchContext object take precedence over the facet configuration?

In short, I'm totally lost as to what does what. Any help is greatly appreciated.

Here is a snippet of my code. What I'm trying to accomplish here is search for a keyword in any asset in the 'DOC' category.

SearchContext searchContext = SearchContextFactory.getInstance(PortalUtil.getHttpServletRequest(request));
searchContext.setKeywords(searchForm.getKeyword());

StringBundler sb = new StringBundler(6);
sb.append("{facets: [");
sb.append("{className: 'com.liferay.portal.kernel.search.facet.MultiValueFacet', data: {displayStyle: 'list', frequencyThreshold: 0, maxTerms: 10, showAssetCount: true, values: ['DOC']}, displayStyle: 'asset_tags', fieldName: 'assetCategoryNames', label: 'category', order: 'OrderHitsDesc', static: false, weight: 1.3},");
sb.append("]}");

List<facetconfiguration> fcs = FacetConfigurationUtil.load(sb.toString());
	
for (FacetConfiguration fc : fcs) {
	searchContext.addFacet(FacetFactoryUtil.create(searchContext, fc));
}
	
Indexer indexer = FacetedSearcher.getInstance();
Hits hits = indexer.search(searchContext);
String[] queryTerms = hits.getQueryTerms();
List<document> docs = hits.toList();
for (Document d : docs) {
	logger.debug("showSearch() - d: " + d.toString());
}
</document></facetconfiguration>

I'm having the same issue. Filtering by categories doesn't work if I add a keyword... My code looks almost exactly like yours. If you've figured it out, I would be very interested in hearing how you did it.

Thanks,

Brian

FYI: This has been confirmed to be a bug in liferay 6.1 GA2

Hi!

I'm trying to search by categoryId in Liferay 6.1 GA 1 and it doesn't work either. Is it a bug in that version too?

Cheers,

Flor.

Please try to search based on assetCategoryIds not assetCategoryNames, then it'll work

Hello.

Does anybody have a solution to this problem?

I'm trying to find items over SearchContext using keywords and filtering across categories. Unfortunately method searchContext.setCategoryIds(categoryIds); has no effect on the search :-(

I have installed Liferay 6.2 GA 4

Thank you very much for help

Zdeněk

my code:

 HttpServletRequest httpRequest = PortalUtil.getOriginalServletRequest(PortalUtil
        .getHttpServletRequest(renderRequest));
    SearchContext searchContext = SearchContextFactory.getInstance(httpRequest);
 
    searchContext.setKeywords(hledanyVyraz);
    searchContext.setEnd(2000);
    searchContext.setStart(0);

    long[] categoryIds = { 846405 };
    searchContext.setCategoryIds(categoryIds);
 
    Facet assetEntriesFacet = new AssetEntriesFacet(searchContext);

    assetEntriesFacet.setStatic(true);

    searchContext.addFacet(assetEntriesFacet);

    Facet scopeFacet = new ScopeFacet(searchContext);

scopeFacet.setStatic(true);

    searchContext.addFacet(scopeFacet);

    Indexer indexer = FacetedSearcher.getInstance();

    Hits hits = indexer.search(searchContext);

    List<com.liferay.portal.kernel.search.document> documents = hits.toList();

</com.liferay.portal.kernel.search.document>
