Extending simple queries: Alternative attributes and values ======
+//This section introduces an extension to simple queries in CQP: the possibility to search for more than one thing, It presupposes that you have read [[cqp:corpus-structure|Section 1]] and [[cqp:simple-queries|Section 2]].//
+===== Alternative values =====
+Often, we want to search for more than one type of expression. For example, we might be interested in differences between the words //love// and //friendship// and so we would want our query to return both words. In such cases, we can use parentheses and the pipe symbol ''|'' to specify alternatives (see [[cqp:special-characters|Typing special characters]] to find out how to type this symbol); ''(x|y)''. For example:
+	[hw="(love|friendship)"]
+Enter this query at the prompt and hit the ''RETURN'' key. You will see that the concordance now contains all word forms belonging to the lemmas //love// and //friendship//. We can include as many alternatives as we want in a query in this way, Try, for example:
+	[hw="(love|friendship|indifference|irritation|hate)"]
+Of course, we can also include alternatives in queries using other attributes, such as ''word'' or ''pos''. The following query finds all instances of the word forms //lovers// and //friends//:
+	[word="(lovers|fiends)"%c]
+And the following query finds all words tagged either ''NN1'' (for “singular noun”) or ''NN2'' (for “plural noun”):
+	[pos="(NN1|NN2)"]
+===== Alternative attributes =====
+We can use a very similar notation to query two alternative attribute-value pairs in a single query. For example, you may want to study the conjunctions //and//, //but//, //or// and //because//; the first three are coordinating conjunctions, tagged ''CJC'' in the BNC. The last one is a subordinating conjunction, tagged ''CJS'' in the BNC. The following query will find all words tagged ''CJC'' and the lemma //because//:
+	[pos="CJC" | hw="because"]
+===== Summary and outlook =====
+This section has shown you how to create concordances containing more than one type of expression. Building on this, you can look at the following sections in any order:
