Full Text Index

What is the effort required to add full-text index & search to Xindice?

It's just a simple Xpath Query using "contains".
I also implemented a case insensitive search by translate.

I guess it's the most unperformant and ugliest way, but it does its job
for me.

I search for all "names" of "things" which contain the searchstring in
one of its nodes.
It looks like this:

"/things/name[contains(translate(../descendant-or-self::*,'ABCDEFGHIJKLM
NOPQRSTUVWXYZÄÖÜ','abcdefghijklmnopqrstuvwxyzäöü'), translate('" +
searchstring +
"','ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜ','abcdefghijklmnopqrstuvwxyzäöü'))]";

Case sensitive it would simply be:
"/things/name[contains(../descendant-or-self::*, searchstring)]"


I hope this helps.

Wolfram,
What did your code look like?
Did you do it in Xindice using
"contains" or externally?

thanks,

Mark

Hi,

I implemented full-text search using a xpath query.

In a 500 documents database it is acceptable fast.

But of course it would be nice to have such a functionallity directly
from the database system.
