Forum OpenACS Q&A: Glossary and datasource for OpenFTS. Any working model?
We are absolutely unable to make work the OpenFTS with the Glossary.
We have also looked at the cvs for oacsc 4.6 and the datasource there.
Neither we can't make work the search code on the cvs.
We are using OACS 4.5 and we have try to implement a datasource for glossary.
I include the code for our actual implementation.
In the search of glossaries we use the following query in the datasource procedure:
select r.revision_id as object_id,
r.name as title,
r.content as content,
r.mime_type as mime,
r.name as keywords,
'text' as storage_type
from cr_revisions r
where revision_id = :object_id
It appears that the 'content' field of the 'cr_revisions' table doesn't fill up when we create a glossary.
Their description it's in the field 'description' of the 'cr_revisions' table.
The code we are using is:
select r.item_id as object_id,
r.title as title,
r.description as content,
r.mime_type as mime,
'' as keywords,
i.storage_type
from cr_revisions r, cr_items i
where i.item_id = :object_id
and i.item_id = r.item_id
and i.live_revision = r.revision_id
and i.content_type = 'glossary'
This goes ok if we run it in plsql.
If we search a word that _exist_ we have the following error at the search webpage.
If the word _doesn't exist_ there is no error.

We also don't understand why appears to exists two different 'object_id'.
One to index the results, and another when we want to search.
Last question. Why don't exists any mean to delete glossary's item??.
I hope you could give us some advice.
Thanks.
