		+	<li>'''Unique'''<br/>
		+	This function will ensure that the resulting collection contains unique elements. The function can operate in two modes, with or without a cache argument. I.e.
		+	<pre>x.unique()</pre>
		+	or
		+	<pre>x.unique(cache)</pre>
		+	The latter expects the argument to be a ''java.util.Set'' that it can use to enforce the uniqueness of the element. This enables the result to be unique in a larger scope then the collection itself.</li>

	A common scenario in p2 is that you want to start with a set of roots and then find all items that fulfill the root requirements. Those items in turn introduce new requirements so you want to find them too. The process continues until no more requirements can be satisfied. This type of query can be performed using the '''traverse''' function. The function will evaluate an expression, once for each element, collect elements for which the evaluation returned ''true'', then then re-evaluate using the collected result as source of elements. No element is evaluated twice. This continues until no more elements are found:		A common scenario in p2 is that you want to start with a set of roots and then find all items that fulfill the root requirements.

-	~~I think it would be valuable if users of p2 that have the need for specific queries could list them here~~. ~~It is not unlikely that some queries might motivate some extension to the current syntax or to how the evaluator works.~~	+
-		+
-	~~===An alternative way of doing things===~~	+
-	Passing instances of the IQuery to an IQueriable is problematic since it is very difficult for the IQueryable implementer to figure out what the IQuery does. When the implementation is based on a database or a remote server, the query needs to be converted into some kind of generic expression. Some special code would need to be written that would make a best effort. It might be able to recognize some queries and then process others locally. Often with very varying performance. Executing a query locally means passing all ~~data over the net or extracting all tuples from a database. For huge repositories, that will be a very resource intensive operation.~~	+
-		+
-	Todays IQuery does have one big advantage though. It can contain java code that does virtually anything to filter the result or even perform actions based on the result. Needless to say, such filtering, or such actions, cannot be performed by a database or a remote server. So clearly, the concept currently encapsulated by the IQuery/IQueryable is needed.	+
-		+
-	Here is a proposal on an alternative solution that would get the best of both worlds. In essence, each query would start with the evaluation of a query expression. Then, if needed, the query result is further processed by a construct very similar to the current IQuery/IQueryable.	+
-		+
-	~~Simplified, the solution would be based on the following two interfaces:~~	+
-	~~<pre>public interface IQueryable {~~	+
-	~~Iterator query~~(~~String expression, Object[] args, IProgressMonitor monitor);~~	+
-	~~Iterator query(Expression expression, Object[] args, IProgressMonitor monitor);~~	+
-	}	+
-		+
-	~~public interface ICollector {~~	+
-	~~Collector collect(Iterator iterator, Collector collector);~~	+
-	~~}</pre>~~	+
-		+
-	The ICollector is basically the same thing as the current IQuery. The key thing here is the separation of concern. An IQueriable can return a result based on a predicate. The ICollector does something with that result.	+
-		+
-	~~Today, you would write something like:~~	+
-	~~<pre>MyQuery query~~ = ~~new MyQuery(collectorArgs, queryArgs~~);	+
-	~~Collector coll = repo.query(query, new Collector(~~)~~, monitor~~);	+
-	~~</pre>~~	+
-	~~If the query does things that must be done locally and is not covered by the query expression language~~, ~~this would now be replaced by:~~	+
-	~~<pre>MyCollector collector = new MyCollector(collectorArgs);~~	+
-	~~Collector coll = collector~~.~~collect(repo.query("some expression", queryArgs, monitor), new Collector~~());	+
-	</pre>	+
-	~~Note though, that any code that just wishes to iterate over the result, would not need the collector at all. It would still be possible to just write:~~	+
-	~~<pre>Iterator itr = repo.query("some expression", queryArgs, monitor);~~	+
-	~~while(itr.hasNext()) {~~	+
-	~~...~~	+
-	~~}</pre>~~	+
-	~~and judging from the current usage of the query, that would be the most common way of doing things. The places where special handling by a collector is needed are very rare.~~	+
-		+
-	We could also allow a more generic Iterator filter, i.e. an Iterator implementation that uses an inner Iterator. With two basic implementations, ContextIteratorFilter and MatchIteratorFilter (corresponding to the current ContextQuery and MatchQuery) such filters would assist in writing general purpose filters to execute locally.	+

	<pre>select(...).limit(100)</pre></li>		<pre>select(...).limit(100)</pre></li>
		+	</ul>
		+	<li>'''Traverse'''<br/>
		+	A common scenario in p2 is that you want to start with a set of roots and then find all items that fulfill the root requirements. Those items in turn introduce new requirements so you want to find them too. The process continues until no more requirements can be satisfied. This type of query can be performed using the '''traverse''' function. The function will evaluate an expression, once for each element, collect elements for which the evaluation returned ''true'', then then re-evaluate using the collected result as source of elements. No element is evaluated twice. This continues until no more elements are found:
		+	<pre>$0.traverse(parent \| select(child \| parent.requiredCapabilities.exists(rc \| child ~= rc)))</pre>
		+	This is of course a fairly naive slicing mechanism. See [[#Currying]] below for more advanced examples.</li>
	</ul>		</ul>
