Hello Nada,
AND/OR searches are still supported in DSpace, but they now must be
typed into the search box (similar to you'd do in Google or similar).
The search form itself has changed to better support the new Solr-based
search engine (added in recent versions of DSpace). The new Solr based
search engine gives us many distinct advantages, in that our entire
browse/search system utilizes it (so that Search/Browse become more
similar in nature) and we are able to now support the "Discover" facets
on homepages / Community/Collection pages, and better searching within
content (including hit highlighting).
But, in terms of boolean searching, you can still use it by simply
typing it into the search box, for example:
qatar AND thesis
You also can limit by fields (if you know the field name/value), for
example:
qatar AND type:thesis OR type:article
At this point in time, the boolean options are not selectable in the
"Filters" section itself. That might be possible to implement in the
future, but we'd want to determine if enough of our users see that as a
useful addition or not (and then locate a volunteer developer to help
make that happen).

Dear DSpace community,
We have upgraded our Dspace to version 5.4 . With the previous version
we had (1.8), we noticed that we can combine search filters using
Boolean search operators (OR, AND,NOT).
But with the upgraded version, we don't have the ability to combine
search filters using Boolean search operators (OR, AND).
In DSpace version 1.8 :
----------------------------------
In DSpace version 5.4 :
----------------------------------
So what if I want to search for this query "qatar" then filter the
results to get only Article *OR * Master Thesis How can I do this with
DSpace version 5.4?
Could you please explain why combing search filters using Boolean
operators feature is not supported with v. 5.4?
