WebMay 17, 2016 · Cypher is a declarative query language created for querying Neo4j ‘s graph data. In Cypher, as in SQL, queries are built up using various clauses. One such clause is the UNION clause that we will discuss in this post. The UNION clause is used to combine the similarly structured results of multiple queries and return them as one output. WebCypher is declarative, and so usually the query itself does not specify the algorithm to use to perform the search. Neo4j will automatically work out the best approach to finding start nodes and matching patterns. Predicates in WHERE parts can be evaluated before pattern matching, during pattern matching, or after finding matches.
