Hi, I've been looking to the implementation of Lucene inside Cocoon, and it's great what this combo is able to deliver. Things will continue to work perfectly until database shows. The 'like' and 'contains' functions in SQL and XPATH queries respectively cannot make much use of the indexing supplied by the corresponding database because they're a sub-string search, while search engines will help here because of the implementation of full-text string searches, so I guess the justification for using search engines rather than query statements for this case is valid.
The problem here ASAIK is that to use lucene you have to supply it with Directory object that points to the location of your data files, which doesn't exist here in case of database. I thought I could mimic the implementation of Lucene inside cocoon but for the Xindice database instead of the spreading files, so I started studying the crawler behavior and if it could be attained with the help of the pseudo protocol implementation for Xindice, but I stuck there with the fact that I'm only mapping URLs to underlying database not to actual directories and files seen to the indexer. On more problem appeared to be there is the information retrieved from the searcher. For many cases that native XML databases help in, it would be of no use to the use to get a URL for his search rather that a brief description to the document he searched (like in searching for items in catalog where the description and the image matters more than the URL that links to it). So I thought if Lucene could be adapted to retrieve documents inside collections rather than URL. Can anybody give me an insight on this issue? Are there any future plans to include search support for XML and other databases? How do you think the support of XQuery language will help in the search process? Thanks. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
