Hi Christian,

The DOI field (in the eprints defaults it's called "id_number" internally - perhaps you use an other field name but same principle applies) should be of type "id" not "text" so that searching it always does an exact match and EPrints doesn't try to apply text indexing to it.

I've added this as an issue on github > https://github.com/eprints/eprints/issues/166

If people change that field to type "id" they would need to reindex the dataset.

Seb.

PS: I think Peter has now fixed it on your repository :-)

Hi all

 

On 3.3.12 I’ve added the DOI filed to the advanced search. Yet searching for a certain DOI e.g. "10.1371/journal.pone.0075761“ leads to several hits.

http://boris.unibe.ch/cgi/search/advanced?screen=Search&doi=10.1371%2Fjournal.pone.0075761&satisfyall=ALL&order=-date%2Fcreators_name%2Ftitle&_action_search=Suchen

 

213 DOI matches " 10.1371/journal.pone.0075761" (Ignoring: "10“)

 

It seems that the doi is split into several pieces (using the dot as delimiter) and therefore ignoring the numbers? What’s the reason for this setting? 

 

Best regards

 

Christian

 

BTW,  search for a doi with simple search (xapian activated) works wonderful.
