Problem in creating Custom Lucene Indexer for a new custom Entity

[Luca Preziati, geändert vor 14 Jahren.]

Hi everybody,
I'm trying to develop a custom index with lucene. My indexer throw this exception when I try to create a new folder, with the code 5 for dividing the existing index.
This is the exception.

Otherwise if I use the folder 0 no problem exist, but I found mixed my older information with my new entity information.

Does anybody have implemented a new lucene index?

[Oliver Bayer, geändert vor 14 Jahren.]

Hi,

I've implemented a new lucene indexer for the xsl content portlet but I didn't get this error. But during development I found it useful if you delete the content of the "data \ lucene" dir before server start and activate "index.on.startup=true" in portal-ext.properties. So the lucene index is always created new.

HTH

[Luca Preziati, geändert vor 14 Jahren.]

Now I'm trying. I call the reindex function from view, and this exception is always raised. I found also that if I put a segment file of another index, all work well. So I think something in creation of this file on filesystem failed, or I forget something.
Any suggestion?

[Luca Preziati, geändert vor 14 Jahren.]

I understand the problem, is related with the 5L index that I try to create. In fact liferay user the companyId to choose in what path build index, and for an optimization i try to put in another folder, separeted from other information.
I think it's a bad choose of design, bacause, why should I mix different information in the same index? For article and all other entity it's a good choice, but I think that can be more understandable separeted the folder.

Hi Luca, Hi all..

I have created a custom struts portlet with 2-3 fields to collect metadata..
I want to search the data based on the metadata that i enter..
I have created an Indexer.java file as well as registered in liferay-portlet-ext.xml..
I am not able to understand how to make a search.jsp file..

Could you please help me with the proper steps that i need to follow..

It would be great if you could help me with a basic template of a search.jsp file and any other file that i would need in accomplishing this task..

Any kind of suggestions or ideas would be of great help..

Thanks..

[Oliver Bayer, geändert vor 13 Jahren.]

Hi Yogesh,

you don't have to write a search.jsp on your own. You need an Indexer class (which you've already created) and also a Search class. Both must be registered inside liferay-portlet-ext.xml.

To write a search class shouldn't be to difficult.
- create a class MyPortletOpenSearchImpl which extends from HitsOpenSearchImpl
- implement the used methods like e.g. the most important one getHits(...)
- inside getHits create a lucene query e.g.

BooleanQuery contextQuery = BooleanQueryFactoryUtil.create();
contextQuery.addRequiredTerm(Field.PORTLET_ID, YOUR_PORTLET_ID);
...
BooleanQuery searchQuery = BooleanQueryFactoryUtil.create();
searchQuery.addTerm(Field.CONTENT, keywords);
...
BooleanQuery fullQuery = BooleanQueryFactoryUtil.create();
fullQuery.add(contextQuery, BooleanClauseOccur.MUST);
fullQuery.add(searchQuery, BooleanClauseOccur.MUST);
...
return SearchEngineUtil.search(companyId, groupId, userId, "YOUR PORTLET", fullQuery, start, end);

So if you put the liferay search portlet on a page you can now search your portlet too without writing your own search.jsp.

If you have any questions feel free to ask.

Hi Oliver,

Thank you very much for your quick reply..
Ok, now atleast i am sure of the steps..but could you please explain in some more detail as to what i should include in my (..)Impl.java file..??

A sample (..)Impl file would be of great help..

Any kind of ideas and suggestions would be of great help..

Thanks in advance..

[Yogesh Prabhu, geändert vor 13 Jahren.]

Hi Oliver,

Sorry, but i am very confused again.. although, i can see my portlet in the search results page now..but i am not getting any results..I believe its not calling the Indexer.java file. I tried putting some print statements inside it, but they were not printed..

I am sure of one thing: We need two class files i.e Indexer.java and (..)SearchImpl.java
Then we have to register these files in the liferay-portlet-ext.xml file.

Now, i believe even my Indexer.java file is wrong..

I am attaching the three files : Indexer.java and (..)SearchImpl.java and also my service.xml file for your reference

Can u please help me with this..

Thanks..!!

[Oliver Bayer, geändert vor 13 Jahren.]

Hi Yogesh,

it seems that your indexer isn't correct if you're using liferay v5.2.3 like me.

Your indexer class must implement the following methods:

public String[] getClassNames();
public DocumentSummary getDocumentSummary(Document doc, PortletURL portletURL);
public void reIndex(String className, long classPK) throws SearchException;
public void reIndex(String[] ids) throws SearchException;

The most important method is the last one (reIndex(String[] ids) because this one is getting called by liferay if you click reindex in controlpanel or if you set the property to reindex on startup.

In your indexer file this method doesn't do anything. But there you should create the document with the data to be searchable and pass it to the SearchEngineUtil.

Sample reIndex method:

public void reIndex(String[] ids) throws SearchException 
{
	Document doc = new DocumentImpl();
	doc.addText(Field.TITLE, PORTLET_ID);
	doc.addText(Field.CONTENT, "content string bla bla");
	doc.addKeyword(Field.GROUP_ID, "12345");
	doc.addKeyword(Field.PORTLET_ID, PORTLET_NAME);

	SearchEngineUtil.addDocument(companyId, doc);
}

You can use luke tool to check what is getting indexed in lucene.

If the indexer is working you can now create a query in searchImpl using the fields you've indexed to get search results.

Greets Oli

[Yogesh Prabhu, geändert vor 13 Jahren.]

Hi Oliver,

Thanks for your reply..i am following your steps of implementing those methods..

Now, when i implement the reindex method in Indexer.java file, i get an error that no such method is defined in HelpdeskEntryLocalServiceImpl.java file which is present in com.ext.portlet.helpdesk.service.impl package

Now what should i write in the reindex method in HelpdeskEntryLocalServiceImpl.java file??

Too many dependency between the files..too many java files to touch i believe..getting confused

Any suggestion would be of great help..!!

Thanks..!!

[Oliver Bayer, geändert vor 13 Jahren.]

Hi,

as I wrote an indexer for the xslcontent portlet I don't have such a dependency. I only have one indexer and one opensearch class. The indexer class determines on which pages the xslcontent portlet is on and then reads the xml and xsl url from portletpreferences to get the content to index.

I don't know your portlet and how it work (how you get the data to display) but maybe you can implement it the same way:

- First determine on which pages your portlet is placed. This can be achieved by using a dynamic query for the portletpreferences table selecting only data which has your portletid in the same collumn.
- Try to get the data of your portlet and save it into lucene.

As a first easier step you can write a static indexer that means put all values directly in source-code. If the indexer and the opensearchimpl are working you can try to get the data dynamically as described above.

Hi Oliver/Yogesh,
I am facing issue with retrieving search data from solr and tried following query.

Map<String, Serializable> attributes=new HashMap<String, Serializable>();
attributes.put("lpName", keywords); //Basically my entity object had 5 types of properties(id,lpName,type,createdDate,modifiedDate)
attributes.put("type", keywords);
SearchContext searchContext = new SearchContext();
searchContext.setAttributes(attributes);
searchContext.setCompanyId(10154);
Hits results = indexer.search(searchContext);

If i pass above query i am getting zero hits. But when i fire my query, solr console is showing below log message.

INFO: [] webapp=/solr path=/select params={hl.fragsize=80&fl=score&hl.snippets=3&start=0&q=%2B(%2B((%2B(entryClassName:com.xerox.ghs.he.portlet.searchentity.model.LibertyProgram))))
+%2BcompanyId:10154&facet.limit=-1&hl.fl=content&hl.fl=content_en_US&hl.fl=title&hl.fl=title_en_US&wt=javabin&hl=true&rows=5&version=1}
hits=3 status=0 QTime=2

Please find my original post and let me know, where i made mistake.
