gianm commented on issue #6189: Lucene indexing for free form text URL: https://github.com/apache/incubator-druid/issues/6189#issuecomment-414172408 Hi @RestfulBlue, it sounds like an interesting idea. Are you imagining adding a Lucene index as a companion to a Druid segment (i.e. adding one as a new column, maybe) or as an alternate format (a new type of StorageAdapter)? One other thing you could look at is using Druid's multivalue dimensions. The idea would be to support text search by tokenizing input fields into arrays and storing them as multivalue dimensions. Then, you can do a search by tokening the search string the same way and retrieving the relevant terms from the inverted index of the multivalue dimension. What do you think?
