In-Depth Information
Gremlin will return a long list of vertices represented by their internal IDs
enclosed in square brackets, with a
v
to indicate that they are vertices.
Unless you have a brilliant memory for numbers, it's difficult to tell which
products have been selected. Repeat the same query, but ask for the
title
property of each result to be shown instead, as shown here:
gremlin> g.V.has('title',CONTAINS,'Graph').title

The first eight topics are mathematical topics on graph theory, which may
or may not be your cup of tea. But notice that the ninth product down is a
DVD. You were looking for graph topics, but you did not restrict the query
to the topic group. Most Gremlin commands are pipelines of input, and
output filters can be chained together. Type the following to select only book
vertices, and
then
search them for the titles of interest:
gremlin>
g.V('group','Book').has('title',CONTAINS,'Graph').title
