[Building Sakai] search tool Q: search just titles / index descriptions

[Zhen Qian]

I think one need to implement EntityContentProducer interface for each content object to be searched for.

You can look for the example codes of ContentHostingContentProducer.java nad SiteContentProducer.java inside the Search module. Specially, for ContentResource objects, there are multiple registered "Digester" instances for various mime types. The digester implementation determines what gets written into the index (through the getContent() call).

I believe the description field is indexed as in DefaultContentDigester, however, it is not in other mime-type digesters. Hence you will find that you can search on the description field value for *.png files, but not for other types of files, e.g. pdf files, or ppt files.

So my answer to both your questions below is that there is no trivial/property-setting solution. It needs code changes in search-impl code.

Thanks,
