"<h2>Search parameters</h2>\n" +
"<p>Lucene offers various query options like boolean, fuzzy or proximity searches. A proximity search would be defined like this: "jakarta apache"~10. This example would retrieve all documents where the term jakarta can be found in the range of maximum 10 words of the term apache. </p><br>\n" +

"<h2>Semantic Search</h2>" +
"<p>The semantic search allows the retrieval of graphs with example graphs." +
"The nodes are referenced by Lucene search statement in square brackets, they can be connected by specifying the " +
"relation (e.g. agentOf, patientOf) followed by the source and the target node referenced by their position in the statement. " +
"Example: \"[Mathias~] [Talking] agentOf 1 2\" defines two nodes. The first one must contain a term near to the term " +
"\"Mathias\", the second one must contain the term \"Talking\" These two are connected by the relation agentOf whereas the " +
"first node is the source, the second node the target.</p>" +
