Hello,
I have been chasing an odd behavior with the Dspace advance search. We
have a couple thousand documents with title control keys that are formatted
like so "EXP22****", i.e. an actual title control key would be EXP227009.
When I perform an advance search on the title control keys using the
"contains" operator with just letters, i.e. title control key CONTAINS
"EXP", the search results come back as expected, displaying all the
documents with title control keys that contain "EXP". However, if I
perform the same search with letters AND numbers, i.e. "EXP22", nothing
gets returned even though there are just as many documents that contain
"EXP22" as there are that contain "EXP".
I'm not seeing any errors in the SOLR or Dspace logs, though oddly the
query on the backend is slightly different for the "EXP" versus the "EXP22"
search, I am not sure why it does this since I am not changing any of the
params on my end besides the search string (see below).
Backend query for "EXP" search (from the SOLR log):

Has anyone seen this before?
(I did try completely rebuilding the search index with no luck, it made no
difference)
Thank you,
