RE: [docbook-apps] Help needed testing CJK search support in webhelp

Hi Robert,
Kasun knows more about the details of the stemmer, but I can point you to the documentation for the porter stemmer we used:

http://snowball.tartarus.org/algorithms/porter/stemmer.html

Currently, English, French, and German are supported. 

You are correct search does not support wildcards in searches, and I don't believe that the algorithm would return results with the same base but different prefixes (i.e. searching for "inhibit" won't show pages with "exhibit"), but I think that's normal for any search engine. 

I'll add "Support wildcards in query string" to the list of future features. I thought I had added it there already but I see now that it's not listed.

Thanks,
David

Hi David,

First of all, thank you for both of you for your work, it looks very promising!
I have a few questions about how search and stemming works:
- Is it possible to add partial matches to the search results? For example, now 
if you search for install, installing, or installed, the same results are 
returned (correctly), because these words all come from install. But if you 
don't type the entire word (say, only 'inst'), there aren't any results.
- Am I right that the search engine does prefix-only matches? (nstall, *nstall, 
etc. does not work)

Regards,

Robert
