+/**
+ * This class represents a simple parsed query statement.
+ *
+ * <p>
+ * A 'parsed query' specifies a document field to inspect and a query string which will be parsed by the document store
+ * to generate the exact query to be performed.
+ *
+ * <p>
+ * The query string will be tokenized into 'terms' and 'operators' where:
+ *
+ * <p>
+ * Terms may be any of the following:
+ * <ul>
+ * <li>single words</li>
+ * <li>exact phrases (denoted by surrounding the phrase with '"' characters)</li>
+ * <li>regular expressions (denoted by surrounding the phrase with '/' characters)</li>
+ * </ul>
+ *
+ * <p>
+ * Operators may be any of the following:
+ * <ul>
+ * <li>+ -- The term to the right of the operator MUST be present to produce a match.</li>
+ * <li>- -- The term to the right of the operator MUST NOT be present to produce a match.</li>
+ * <li>AND -- Both the terms to the left and right of the operator MUST be present to produce a match.</li>
+ * <li>OR -- Either the term to the left or right of the operator MUST be present to produce a match.</li>
+ * <li>NOT -- The term to the right of the operator MUST NOT be present to produce a match.</li>
+ * </ul>
+ *
+ * <p>
+ * The expected JSON structure for a parsed query is as follows:
+ *
+ * <pre>
+ * {
+ * "parsed-query": {
+ * "field": "fieldname",
+ * "query-string": "string"
+ * }
+ * }
+ * </pre>
