There is a BUG in the Facets Search.

Steps to reproduce:

  1. Search by the term "test" and press return. Now take not of the values in the "Categories" Facet in the right of the screen
  2. Hit the browser refresh, and you will notice that the "Categories" Facet values have changed !

I'm pretty sure the issue is that there is no stable secondary sort of the terms with the same counts. When I refresh it, occasionally the categories with count = 2 change.

Is this the problem you're reporting?

If so I believe it is a duplicate of this bug: blevesearch/bleve#335

Mhh I read #335.

For me, the problem is not just the ordering or counts. I am getting different actual Categories each time:

Use this url: http://localhost:8099/search/?q=test&p=1

Refresh on that URL and i get:

Testing and automation (6)
Open Document editors (3)
Graphics (2)
PostgreSQL (2)
Lightning talks (2)

a second later, I refresh on the same URL and i get:

Testing and automation (6)
Open Document editors (3)
Perl (2)
Lightning talks (2)
Geospatial (2)

I still think its the ordering. The request shows the top 5 categories, and we sort by the count. The first two are obviously 'Testing and automation' with count 6 and 'Open Document editors' with count 3. That leaves 3 spots remaining, but there are more than 3 categories that all have the count of 2.

How does it decide which to show? It doesn't, that is why sometimes you see different category names. If we imposed a secondary sort on the categories after the sort by count, it would give deterministic output.

Thanks for the explanation. Make sense now.

I was playing with it, with a colleague today at work, and testing at the JSON level, and we were thinking "thank god its Friday, because we see things" :)

If you can do that fix would be great.

I tried this again today, as i need to start using facet search for the project i am working on.

I did a go get -v on the various bleve repos to update them.
In fosdem-search repo, go build and then run ./fosdem-search, to see if the UI bug is still there. Yes i am still getting it.

Any chance this could be fixed ? Or maybe it already has been ?

I have pushed a fix to blevesearch/bleve#335 I have verified fosdem-search locally, but not redeployed the hosted version.
