Some Background info : In our application, we have a requirement to update large number of records often. I investigated solr child documents but it requires updating both the child and the parent document . Therefore, I'm investigating adding frequently updated information in an "auxillary document" with a custom defined "parent-id" field that can be used to join with the static "parent document". - basically rolling my own child document functionality.
This approach has satisfied all my requirements, except one. How can I facet upon a field present in the auxillary document? First, here's a gist dump of my test core index (4 docs + 4 aux docs) https://gist.github.com/anonymous/2774b54e667778c71492 Next, here's a simple facet query only on the aux . While this works, it only returns auxillary documents https://gist.github.com/anonymous/a58b87576b895e467c68 Finally, I tweak the query using a SOLR join ( https://wiki.apache.org/solr/Join ) to return the main documents (which it does), but the faceting returns no results. This is what I'm hoping someone on this list can answer . Here is the gist of that query https://gist.github.com/anonymous/f3a287ab726f35b142cf Any answers, suggestions ? Thanks
