Search: search box returns 0 results when searching for existing/duplicate MD5

[sbarbosadataverse]

I was trying to locate a duplicate md5 in dataset with a large number of files but the search feature returns 0 results. MD5 i tested was tagged as a duplicate during file upload. I put the md5 into the search for the entire dataset, with 0 results.

@sbarbosadataverse can you please provide the md5 you were searching on?

MD5: a0d3c0496ea2fa4c1795d441c2fecc8a
message during file upload: A file with this MD5 already exists in the
dataset.

@sbarbosadataverse thanks. Here's an example of a successful search from before for an MD5: #2038 (comment)

And here's a live example: https://dataverse.harvard.edu/dataverse/harvard?q=fileMd5:48a76222cf5c06cb4f2d8f75cc0caa63

@pdurbin is it because i'm not using advanced search? just putting it into the file page search box?

[sbarbosadataverse]

@pdurbin were you able to replicate my issue with the md5 i sent?

[sbarbosadataverse]

@pdurbin any update? Thanks

The file page search doesn't search everything currently. It runs a query in the db. What we really want is for this to go through Solr, but we'll need to resolve how we handle versions first.

So, solutions:

1. Add Solr search here, tracked by issue Use Solr for file listing on dataset page #2455
2. Add md5 to the limited search provided here.

(Not so great) Workaround: do the search from the dataverse page

@sbarbosadataverse when I log in to production and go to https://dataverse.harvard.edu/dataverse/harvard?q=fileMd5:a0d3c0496ea2fa4c1795d441c2fecc8a which has the MD5 you're looking for I can tell that the file being found is "2010 47.45 Le Blanc.pdf". Does that help? The key to this is knowing that "fileMd5" is the Solr field to use. Rather than hacking the URL, you can also just type "fileMd5:a0d3c0496ea2fa4c1795d441c2fecc8a" in the search box.

searching using Phil's suggestion works fine!

@sbarbosadataverse great! Passing to QA at https://waffle.io/IQSS/dataverse

@pdurbin @sbarbosadataverse @scolapasta It seems from this ticket that Sonia has a workaround but is there a feature request here or expectation that md5 is searchable directly from the UI.
Also, what prompted this ticket is confusion about how duplicate files with different names but same md5s are reported, already opened in a separate ticket: #2467

I'm closing this but opening a separate ticket to allow searching on md5 from UI, #3436
