+#### Tips
+
+Without index, NEO4J query will be very very slow. So before you start, you should add some index:
+
+```cql
+CREATE INDEX publication_title_hash_index FOR (p:Publication) ON (p.title_hash);
+CREATE INDEX publication_dblp_key_index FOR (p:Publication) ON (p.dblp_key);
+CREATE INDEX publication_doi_index FOR (p:Publication) ON (p.doi);
+```
+
 ### Only crawl the paper after specified year
 
 e.g. crawl the paper after 2016 (include 2016)
