+<p>CQL stands for Contextual Query Language. The main purpose of CQL is to represent queries
+    to information retrieval systems. In fact, CQL is commonly used together with the Search
+    Retrieve URL (SRU) protocol to represent URL-friendly search queries.</p>
+    
+<p>In KorAP, we support basic CQL as defined in the <a
+href="https://www.clarin.eu/content/federated-content-search-clarin-fcs">CLARIN
+Federated Content Search (FCS)</a> specification for basic search. KorAP does not
+    support other operators and modifiers than AND and OR, such as REL and PROX. </p>
