Guys, We have a website running Solr indexing books, and we use a facet to filter books by author. After some time, we detected that this facet is very large and we need to create some other feature to help finding the information.
Our product team asked to create a page that can show all authors by it's initial letter, so we can distribute this query easier. Is it a feasible solution to create another field containing only the initial letter for the authors? Using this approach we will be able to filter the authors using this newly created field. Do you think there will be any performance penalty on creating a couple of fields with the initial letter of these other fields (author, publisher)? I guess that this approach is way easier than other solutions we came up with. Am I missing other alternatives? Thanks, Alexandre
