Re: [Exist-open] Query: XQuery/Keyword Search in eXist 1.4

[Sidharth A. <sag...@as...>]

Thanks for the reply. I understand the concept. But it looks like searching
for an exact phrase or word in the document,
What if i want to provide a search button in the webpage, where a user can
enter any phrase, which is then searched over the collection specified.

For ex: I have a collection called "TestColl" in which i have 50 XML
instances, how will i write this query using lucene.
Similar type of  example is given in "
http://en.wikibooks.org/wiki/XQuery/Keyword_Search" but thats for eXist 1.3.
