Hello,
Does BaseX have built-in support for faceted search? I see that there's an easy way to get the facets for the entire database using
index:facets(), but is there way to get search results that includes a similar list of facets, based only on those results?
Thanks,
GregMS

Hi Greg,
currently there is no out-of-the-box functionality, yet there is an EXPath Specification that handles facets:

We have not yet implemented it in BaseX, but we might eventually if there is enough interest and maybe even a sponsor :-)
Would that module cover your needs?

Hi Michael,
Thanks very much for your reply. I wasn't aware of this spec. Yes, such a module would certainly serve my purposes. Currently I'm mainly interested in what the spec calls drill-sideways, though I'm sure the other options would be useful in other applications. I think such a module is very important, since faceted searching is such a common use case. I'm sure it's possible for the application to provide its own facet functionality in an ad-hoc way using XQuery, but I don't know whether such code would make use of indexes under the hood and therefore be performant against large document stores. No doubt having not only the standardized approach but also fast, index-based implementation would be extremely useful -- and in fact indispensable for many web applications.
What is meant by "sponsor" in this context? Financial, administrative, or something else?
Thanks,
Greg

Hey Greg,
thanks for your reply.
yes, I think a „native“ i.e. java based implementation might make use of more elaborate optimizations. However maybe we could manage to implement (parts of?) the EXpath specification in XQuery to gain some insights and have this, eventually, replaced with a more powerful implementation.
Sponsoring can be of any form, usually it means organizations or companies pay for a feature; but contributing code and or ideas is at least as good and valuable :-)
I think Christian already had some talks with a potential sponsor, but as he is on vacation I think well have to wait until next week for his feedback.

Hi All,
I would love to see faceted search capability. Sorry, but I can't offer sponsorship.
Two things I would love to see in BaseX are faceted search capability (fast, index-based) and role-based security.
Best,
Tim Finney

Hi Tim,
thank you for joining the discussion, sponsoring is by no means a requirement (sorry if I made it sound any other way! :-)).
What would you think, does the EXpath Facet proposal cover some or most of your use-cases?

Hi Michael,
The EXpath facet proposal does appear to cover most use-cases I can think of. I believe that indexes are required to make faceted searches work quickly with large document sets.
Best,
Tim Finney

Hi Tim, hi Gregory,
As outlined by Michael, we are currently investigating if there will be enough (human and financial) resources to implement the EXPath Facet Module [1]. To everyone: We are very interested in feedback on this proposal!
As outlined by Tim, one crucial aspect will be the question if we can rewrite the functions of that module such that they will be sped up by index structures. From what I’ve seen so far, it won’t be that obvious how to proceed, but I’m currently thinking about possible solutions.
Cheers,
Christian

Written for BaseX 8.4. BaseX may have changed since: please check the current documentation.
