Liferay 7 Indexing issue

[Jiten Vaghela，修改在6 年前。]

Hi all,

I am creating one learning project in which I'm integrating indexing with Liferay 7 ce ga 4.
I found reference blog to create indexer in Liferay 7 which is:
https://dev.liferay.com/develop/tutorials/-/knowledge_base/7-0/creating-a-guestbook-indexer

I Followed all the steps but still I'm unable to create indexer.
Here, I pasted code which I did:

TestIndexer.java

	@Reference
	protected IndexWriterHelper indexWriterHelper;

	@Reference
	private TestLocalService _testLocalService;

}
</test></test>

I follow all the steps described in above linked document but still i'm getting this below error

Error: The type javax.portlet.PortletResponse cannot be resolved. It is indirectly referenced from required .class files


Can Any one help me to solve this issue?

[Andrew Jardine，修改在6 年前。]

Hi Jiten,

That error normally means that there is a class that is required that is not on the classpath. Can you share with us what your bnd file looks like? .. Throw in your gradle file while you are at it.

Andrew Jardine:

Hi Jiten,

That error normally means that there is a class that is required that is not on the classpath. Can you share with us what your bnd file looks like? .. Throw in your gradle file while you are at it.

Thanks for the revert back. I have fixed the error for javax.portlet.PortletResponse . I added compileOnly group: "javax.portlet", name: "portlet-api", version: "2.0" in gradle setting.

However, I'm getting new error for following.

[Class com.wp.test.search.TestIndexer is not assignable to specified service com.wp.test.model.Test]

Not sure, what still missing.

This is my BND file.

Bundle-Name: test-service
Bundle-SymbolicName: com.wp.test.service
Bundle-Version: 1.0.0
Liferay-Require-SchemaVersion: 1.0.0
Liferay-Service: true
Export-Package: com.wp.test.search.service.permission,\
		com.wp.test.search

This is my Gradle File

dependencies {
	compileOnly group: "biz.aQute.bnd", name: "biz.aQute.bndlib", version: "3.1.0"
	compileOnly group: "com.liferay", name: "com.liferay.osgi.util", version: "3.0.0"
	compileOnly group: "com.liferay", name: "com.liferay.portal.spring.extender", version: "2.0.0"
	compileOnly group: "com.liferay.portal", name: "com.liferay.portal.kernel", version: "2.6.0"
	compileOnly group: "javax.portlet", name: "portlet-api", version: "2.0"
	compileOnly project(":modules:test:test-api")
}

buildService {
	apiDir = "../test-api/src/main/java"
}

group = "com.wp.test"

[Andrew Jardine，修改在6 年前。]

Can you show me the BND for your test-api module? That is the one that is most important in this case because you need to make sure that the packages that contain the classes you want to reference (in your test-service) are actually exposed. Remember that the proper implementation is that your "users" of the service will actually reference the API and allow the OSGI to inject the impl at runtime.

[Jiten Vaghela，修改在6 年前。]

Hello Andrew,

Following is BND file for test-api.

Bundle-Name: test-api
Bundle-SymbolicName: com.wp.test.api
Bundle-Version: 1.0.0
Export-Package:\
	com.wp.test.exception,\
	com.wp.test.model,\
	com.wp.test.service,\
	com.wp.test.service.persistence
-includeresource: META-INF/service.xml=../test-service/service.xml

I think, com.we.test.model is exported in api.

Other thing, I noticed in journal article's code, its referencing Indexer.class as service, where as in the user class, its mentioned to use custom entity for the same. Is that something, that needs to be looked on? ref: JournalArticleIndexer

[Andrew Jardine，修改在6 年前。]

I think you want to follow the method that is used for the JournalArticle. I am trying to dig up something from the last time I did this and I think it is on another machine that is not accessible to me right now. If my memory serves me correctly though, I use the Indexer.class service for my custom implementation.

.. you can always check to see if your Indexer is registered by using the IndexerRegistryUtil to get the list of registers and then check to make sure that yours is in it.

[Jiten Vaghela，修改在6 年前。]

Thanks for answer.

I solved this problem. Now I have new problem.

Indexer works fine. I used "Elasticsearch" google chrome extension to find indexed data. I got indexed document in that.

When i try to get indexed document using "Hits" in searching portlet I don't get data.

my code is:

public void keywordSearch(RenderRequest renderRequest, RenderResponse renderResponse){
		try {

			HttpServletRequest request = PortalUtil.getHttpServletRequest(renderRequest);
			
			SearchContext searchContext = SearchContextFactory.getInstance(request);

			searchContext.setKeywords("test");
			searchContext.setAttribute("paginationType", "more");
			searchContext.setStart(0);
			searchContext.setEnd(10);
			Indexer indexer = IndexerRegistryUtil.getIndexer(Test.class);
			
			System.out.println("Indexer Name ::"+indexer);
			Hits hits = indexer.search(searchContext);

			System.out.println("hits.length :::"+hits.getLength());
System.out.println("hits :::"+hits);
			
		
			
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

When I have these kids of problems I usually go back to basics and try using a different branch of the API to see if I am able to retrieve my data using a simpler query. Try using something like this to see if you can get your records --

// get your kywords
String keywords = ParamUtil...

// get your search context as you have already

searchContext.setKeywords(keywords);

// build a basic query
BooleanQuery searchQuery = BooleanQueryFactoryUtil.create(searchContext);
searchQuery.addRequiredTerm(Field.ENTRY_CLASS_NAME, Test.class.getName());

// run it
Hits hits = IndexSearcherHelperUtil.search(searchContext, searchQuery);

Set a break point and check out the hits results. Start with that and see if you get something back. If you do then you know that the culprit must be the indexer logic that is constructing the query -- perhaps it is adding something as required that needs to be optional. I'll tell you this, with the current query that you cut and paste? no way I am going to read that first

Hello All,

I am working with Liferay 7 CE GA 6. I want to add a search functionality with custom entity. I have created an Indexer with help of following :
https://dev.liferay.com/develop/tutorials/-/knowledge_base/7-0/creating-a-guestbook-indexer

I followed all the steps from that doc but I am unable to find the records using "Hits". It's size returns 0.

Following is my code:

Hi Anna,

The first thing I would suggest doing is querying your elasticesearch directly to make sure that the records are in fact in there. I use postman to do this,but there are many options out there, including browser based plugins.

Can you try that first to make sure there is actual data to retrieve?

Hello Andrew,

Thanks for the reply.

Yes, there are actual data to retrieve and I tried with your suggestion. But I am not getting any records.
