RVK Search doesn't find Classes although they exist #296

Closed DennisTobola closed 5 years ago

DennisTobola commented 5 years ago

When I'm searching "Neuronale Netze" in RVK I get no results. However, when I'm just searching "Neuronale" i get 3 results which all contain "Neuronale Netze":

This is a bug in DANTE. Here are example queries:

StiftungAusNachlass commented 5 years ago

Thanks, this is not the expected behaviour, right. It is maybe an elasticsearch-issue, i have to do further analyses

stefandesu commented 5 years ago

I'm closing this issue as the RVK is currently served by jskos-server and correctly returns results:

https://coli-conc.gbv.de/rvk/api/suggest?search=Neuronale+Netze&voc=http:%2F%2Furi.gbv.de%2Fterminology%2Frvk%2F&limit=100&count=100&use=notation,label&language=de

StiftungAusNachlass commented 5 years ago

It was an error in elasticsearch-wildcard-analyzer. Probably fixed by programmfabrik with next easydb-release 5.50.0 (planned publication on 02.05.2019)

StiftungAusNachlass commented 5 years ago

I installed the latest release and now results are returned: https://api.dante.gbv.de/suggest?search=Neuronale+Netze&voc=http:%2F%2Furi.gbv.de%2Fterminology%2Frvk%2F&limit=100&count=100&use=notation,label&language=de

Is this the expected result, or would you expect only results which contain the whole searchstring at once?

stefandesu commented 5 years ago

I'm not sure (@nichtich ?), but at least the order seems off. Those that contain the whole search string should be at the top, shouldn't they? But I guess you don't have any control over that.

StiftungAusNachlass commented 5 years ago

The results are sorted alphabetically at the moment.. :-)

stefandesu commented 5 years ago

@StiftungAusNachlass Any particular reason why? I would have expected them to be sorted by relevance.

StiftungAusNachlass commented 5 years ago

We have some use cases, where we just take the results and put them in dropdowns. I think that's the only reason, which we could bypass by a sort-parameter for /suggest. I am gonna examine, if a order by relevance is responded by easydb-api at all.

StiftungAusNachlass commented 5 years ago

Ok, with the order via _score, the result for "neuronale netze"-suggest would be:


    "neuronale netze",

I am gonna ask Jakob how to form the sort-parameter.
