I had not explored the index:facets() function—interesting. However, since my goal is to get values straight from the indexes, I think using the facets doesn’t help, since the alternative is to just do an XPath over the attributes in my index XML.

Cheers,

E.

Hi Eliot -

If I'm following correctly, could you use `index:facets()`? E.g.

index:facets($db)//attribute[@name='bundles']//entry/text() => distinct-values()

Can the bundles attribute have multiple tokens?

Best,

Bridger

Using the attribute index I can get all attributes of a specific name that have a specific value or token (db:attribute()) and I can get all the values for all attributes that start with a specific prefix (index:attributes()) but I don’t see a way to get, from the index, all the values for all the attributes of a specific name.

Have I missed something?

My use case is I have an index over my docs where each index entry is of the form:

  <doc-to-bundle-index-entry key="10503999" filename="c_DataCertification.dita" dbpath="product/data-certification/concept/c_DataCertification.dita" bundles="bundle-platcap-platform-capabilities"/>

And I would like the distinct-values of all the @bundles attributes. There are about 40K entry elements.

Of course I can do:

doc-to-bundle-index/doc-to-bundle-index-entry/@bundles ! tokenize(., '\s+')

=> distinct-values()

And that seems plenty fast, but it seemed like there should be a way to do it with the indexes alone. But it may be that the query on the @bundle attribute actually uses the index anyway…

Cheers,

E.
