I am trying to organize my solr collections as it follows:
1 - I have a real collection for each month of multiple years;
2 - I have an alias for each year that includes all the relevant months;
3 - I would like an alias that includes all years;
4 - I would like an alias that includes different kind of dataset of the previous step;
Since I cannot create an alias including aliases only, I created a real empty collection for creating the alias which includes all years (3rd step) and managed to make it works.
However I cannot manage to to reach the last step: although I can create the alias that wraps all datasets, if I try to make a query on this alias I get an error reporting that solr cannot find the alias of a year (the 2nd step) although this year is included in an alias included in the last one.
The Solr documentation reports:
"Aliasing allows you to create a single 'virtual' collection name that can point to one more real collections. You can update the alias on the fly."
Is there a way to create alias of aliases in Solr?
