Source Directory Must Be Lowercase

[lukehsiao]

When running Mindbender after running my DeepDive project, I got this error:

lh@dd:~/repos/HardwareDeepDive$ mindbender search update
Launching Elasticsearch for http://localhost:9200 from /home/lh/repos/HardwareDeepDive/search
Deriving mappings for relations table_dump part_num_mentions part_stg_temp_min_label gold_data part_stg_temp_min
Creating index HardwareDeepDive
Elasticsearch error: InvalidIndexNameException[[HardwareDeepDive] Invalid index name [HardwareDeepDive], must be lowercase]

Simply renaming my ~/repos/HardwareDeepDive directory to ~/repos/hardwaredeepdive seems to have solved the problem.
