Subject Re: Should I Use Xindice for web-searchable XML Docs?

According to

The functionality you require should appear in the recommendations, then subsequently appear
in software implementations, sometime in the (not too distant) future...

Is that what you had in mind?  The w3 docs are an interesting read...

  In fact, with XPath, you can search for node values and search for a particular pattern
in it. You are not limited to attributes values. But i don't think this kind of retrieval
will be very fast.

  This also may be not very efficient as you can't search for regular expressions in the content
(i'am almost sure, be it should better be checked).

    I am not sure about the 'ranking'. My understanding, correct me if I am wrong, neither
XPath nor Xindice is designed for full-text retrieval. So, the 'ranking' is out of question,
if it means the relevancy of the return.

    One thing you may want to know is that Xindice doesn't support XPath which refer to an

    XDataFinder, another way to browse XML database

    Thanks Bob, 

    Yes, that does help a lot as far as my concerns about performance.  I'd also like some
feedback on just the overall idea of what I want to do with xindice.  Has anyone used it as
kind of a 'search engine' like I'm talking about?  Is the XPath support in Xindice fairly
robust?  I'm not sure yet whether or not it's an absolute requirement, but it seems like it
would be pretty difficult to be able to *rank* search results.... anybody done anything like
this with Xindice? 

    Thanks again!

      I've stress tested Xindice with 30000 documents (62 kb each). The
      performance was acceptable, as long as I set up indexes relating to what I
      was looking for. The indexes are essential. Also, you're going to probably
      want to implement some type of connection pooling. I implemented connection
      pooling based on the following three classes/interfaces in
      org.apache.xindice.util: ObjectQueue (can be used right out of the box, very
      nicely written), ObjectPool, and Poolable. It made a big difference in

      It sounds like your xml is read only, so you don't have to worry about
      transactions, locking, security, etc. If you are interested in implementing
      some type of security, there is some nice code in the
      org.apache.xindice.core.security package that you can use as a foundation.

      Hope that helps.
