[Dspace-tech] Diacritic Searches in Version 1.5.1
Diacritic Searches in Version 1.5.1 When searching using a diactitic search term Dspace interprets the diacritic characters incorrectly, Therefore no hits are returned. For example when you search on Sánchez an author that exists in our system Dspace translates this Author to Sánchez. In version 1.4 searching does not change the diacritic form of the search term, returning the expected hits. Has anyone encountered this bug and is there a fix or workaround we can apply to fix this issue.

[Dspace-tech] PSQLException OID ### does not exist
Message: 2 Date: Wed, 01 Apr 2009 21:01:58 -0700 From: Kim Griggs kim.gri...@oregonstate.edu Subject: [Dspace-tech] PSQLException OID ### does not exist To: dspace-tech@lists.sourceforge.net dspace-tech@lists.sourceforge.net Message-ID: c5f986c6.a42c%kim.gri...@oregonstate.edu Content-Type: text/plain; charset=US-ASCII We are upgrading to 1.4.2 to 1.5. Java 1.5. Postgres 8.1. After running the indexer we are getting internal errors on the high level browse by pages. The error is: org.postgresql.util.PSQLException: ERROR: relation with OID 54778762 does not exist Oddly the community level browse bys work. I read that it might be a postgres thing and upgrading to 8.3 might fix it. Before I go through that I am looking for confirmation. Has anyone seen this problem and how did you fix it? Thanks. Hi Kim You need to stop the handle-server, tomcat, and then postgres in that order. Then just restart them in the reverse order. Wait 30 seconds for each command to complete before executing the next command. Example: 1.) svcadm disable handle-server 2.) svcadm disable dspace 3.) svcadm disable postgres 4.) svcadm enable postgres 5.) svcadm enable dspace 6.) svcadm enable handle-server This is how I resolved this issue.

[Dspace-tech] Searching Exception in Dspace
We get hundreds of exceptions daily which are related to searching in
DSpace. The get request is obviously not created by DSpace because when you
do a simple search or advanced search through the interface DSpace does not
create the request in the format seen in the exception message. Therefore I
concluded the request is being created by users or another system that
interfaces with DSpace. Doing some research I discovered that the googlebot
forms the query which creates the exceptions. For the benefit of others who
are getting their inbox flooded with these exception messages here is a work
around. Insert this code into the top of the buildQuery Method in
QueryArgs.java. By applying this code the query will return no results in
the search list rather than throw an exception. This solution may seem to be
extreme however the googlebot is the source of the exceptions and needs to
create a request that conforms to the DSpace specifications rather than
querying with malformed get requests.
public String buildQuery(HttpServletRequest request)
{
// The googlebot creates it's own get request which is not in a
format recognized by dspace
// Generally the get request is formed by dspace through interaction
with the user interfaces such as the Search and Browse Interfaces
// googlebot sample request:
http://eggloop.its.queensu.ca/simple-search?advanced=truequery1=hamster
// The code below will determine if advanced is defined and if so it
must by definition also define field1
// if field1 is not defined it is not considered a valid query and
returns no results
// Ron Stevenhaagen - 27, Feb 2009
if(request.getParameter(advanced) != null
request.getParameter(field1) == null)
{
String Dummy = ;
return Dummy;
}

[Dspace-tech] Withdrawn items
We have been withdrawing items from our collections from time to time when authors decide they would like to restrict their submission. We can verify that the item is no longer viewable through the browse and search functions in dspace after making the withdrawal. However we recently discovered that the restricted items are still viewable through a web browser by entering the URL of the pdf located in the bitstream directory. This is also evident when I visit other dspace sites on the web. This appears to be a security issue/bug in DSpace as the items are not actually withdrawn but only partially hidden. Has anyone else encounter this issue and if so is there a fix or work around. We also discovered that when an item is withdrawn the browse function in dspace throws the following exception. The browse lists still contain a reference to the withdrawn item but should exclude the withdrawn item from its list because the item can't be browsed. When the item is reinstated the exceptions stop. This also appears to be a bug.
