copied!<p>The below code will add a synonym to a rootword: (You'll probably want to check if your 'word' and 'synonym' is already in the db so you could just create a relationship)</p> <pre><code>public static void AddNodeToDb(IGraphClient graphClient, string index, RootWord word, RootWord synonym) { if (!graphClient.CheckIndexExists(index, IndexFor.Node)) { var configuration = new IndexConfiguration { Provider = IndexProvider.lucene, Type = IndexType.fulltext }; graphClient.CreateIndex(index, configuration, IndexFor.Node); } var wordReference = graphClient.Create(word, null, GetIndexEntries(word, index)); var synonymReference = graphClient.Create(synonym, null, GetIndexEntries(synonym, index)); graphClient.CreateRelationship(wordReference, new IsSynonym(synonymReference)); Console.WriteLine("Word: {0}, Synonym: {1}", wordReference.Id, synonymReference.Id); } </code></pre> <p>The 'GetIndexEntries' method gets the entries you'll want to put in the index for your object (RootWord), as you only have term, that's easy:</p> <pre><code>private static IEnumerable<IndexEntry> GetIndexEntries(RootWord rootWord, string indexName) { var indexKeyValues = new List<KeyValuePair<string, object>> { new KeyValuePair<string, object>("term", rootWord.Term) }; return new[] { new IndexEntry { Name = indexName, KeyValues = indexKeyValues.Where(v => v.Value != null) } }; } </code></pre> <p>So, say you've entered 'Ace', 'Great' You can query (using Cypher) as:</p> <pre><code>START n=node(0) MATCH n-[:IS_SYNONYM]->res RETURN res </code></pre> <p>(assuming node 0 is your root word you want!) which will return the 'Great' node. At the same time, because we also created a fulltext index, you can search for the rootword using the following code:</p> <pre><code>public static void QueryTerms(IGraphClient gc, string query) { var result = gc.QueryIndex<RootWord>("synonyms", IndexFor.Node, "term:" + query).ToList(); if (result.Any()) foreach (var node in result) Console.WriteLine("node: {0} -> {1}", node.Reference.Id, node.Data.Term); else Console.WriteLine("No results..."); } </code></pre> <p>Once you have those nodes, you can traverse the 'IS_SYNONYM' relationships to get to the actual synonyms.</p>

Querying!
