Subject Re: my 8 questions about GreenStone system
Hi,

I'm new to greenstone myself and am still assessing it in comparison to
other full text library systems.

I have found the greenstone support form very helpful and quick way of
getting answers to my questions.

http://www.greenstone.org/english/support.html

I suggest it is the best bet but I think I can answer one or two questions.

>1.About searching methods.
>Does GreenStone version 2.38 support ranked searching ? If yes, how could
I do
>to switch between ranked searching and boolean searching ?
YES is supports ranked
choose 'preferences' to use boolean

>2.About remote handling.
>Is it possible to add new documents to the collection remotely?. Once, I

Don't know. I am using the Win 2.38 as well.
I'd like to know. I was looking at the source and thinking about adding a
'browse' button to aid file selection and upload.

>4 About metadata.

I think you better use the support form I mentioned above, but here are
some ways
1. I believe this can be done by using the htmlplug metadata options.
2. The Organizer (available for download at the www.greenstone.org )
3. editing files by hand
4. I saw a demo of the setup that GLSN have created. They have easy to use
forms. http://www.glsn.com/

If
>yes what should I start form ? Do you have any better solution ?

See 'tagging document files' (p36 dev guide)
I haven't tried it yet but hope to soon.

>5. About assigning the value for metadata.
>You can see that the Dublin Core information for each document□in MSWord
>format□is available inside the properties information of themselves
(MSWord
>supports that) so how can we reuse that information. I looked at wvWare
output
>file. Only Title field is available. So what can be the solution

I think WordPlug(using wvWare) gets Author and Title (p29 dev guide).
Probably have to look at both.

>7. About Date format.
>I major about the Date information, and want to classify document on
Date. How
>can I add DateClassifier into my collection. Can you show me step by step
to
>do it. I'm sure that it will be useful for other people. I tried to add
format
>string to the collection config but the Date tag doesn't appear in the
>navigation bar.

Um. the support form. (p37 dev guide - but once again I haven't tried it)

>8. About import directories
>Is import directory is a temporary directory ? After building the
collection,
>is it deleted ? The reason I ask so because I couldn't see the import
>directory in my collection. But the system store my input file in the
>tmp build* directory ! So if I remove the tbuild* in the tmp
directory,□does
>the system work properly ? Some time when I build the collection again,
>document content disappears. Is is the result of remove files in tmp
directory.
Sorry.

I hope this helps a little.
