How to have properties contribute to the node's TEXT index?

hbf — Tue, 28 Oct 2008 15:57:51 GMT

Dear list,How can I achieve that a property's value is indexed in such a way that a Lucene TEXT query finds it?More precisely: I have a custom model, for instance like this: <type name="my:node"> <title>My node</title> <parent>cm:content</parent> <properties&g

I too would like to know how this is done, if its even possible.

I've been able to create custom models and extend the web client through the advanced search, but no idea how to do that for the 'simple search'.

It is possible to add custom properties to simple search, see

Thanks Loftux. Works like a charm. What I didn't realize was that I had to change the URI (duh).

Here is an example of what I did:

mymodel.xml


<namespaces>
   <namespace uri="http://www.mycontent.com/model/content/1.0" prefix="mycontent"/>
</namespaces>

<type name="mycontent:customType">
   <title>My node</title>
   <parent>cm:content</parent>
   <properties>
      <property name="mycontent:customProperty">
         <type>d:text</type>
      </property>
   </properties>
</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

web-client-config-custom.xml


<config>
   <client>
      <simple-search-additional-attributes>
         <qname>{http://www.mycontent.com/model/content/1.0}customProperty</qname>
      </simple-search-additional-attributes>
   </client>
</config>
‍‍‍‍‍‍‍‍‍

I have found it to work with both custom types and aspects.

Thanks a bunch!

This is definitely one way to solve the issue: search not just in TEXT but in all other proberties.

I would be interested in a solution that indexes my properties to TEXT. Is it possible?

The reason I ask is that our custom models have many, many properties, so using the former approach results in huge Lucene queries: TEXT:"blabla" OR @my\rop1:"blabla" or @my\rop2:"blabla" OR …

Thanks,
Kaspar

Workaround: you could provide your own content transformers to prepend or append the property values when transforming to text/plain.

If I were you, I'd first ask the Lucene guys if it is at all possible, and then try to find a way to "plug" it in Alfresco.

Hi

TEXT is not a real field ionr he index. It is expanded at query time. By default it maps to d:content -> all properties of type content.
You can define what TEXT (and ALL) means on SearchParameters objects. You can add other fields.
There is no easy way to change the default - before you ask.
