Could somebody please explain how to use search within jackrabbit repository 
to find some set of nodes?

Jackrabbit search works as specified by the spec. See section 6.6.

Or is there anything in particular you are interested in?

Well, okay, but even if I will have some property to search for, will I be
able to use contains() function in similar way as starts-with?

Well, I'm just testing the JackRabbit's performance, i'd like to know the
speed I could archieve if I need to search for something.

because of limitations of existing commercial repositories complex
path operations have been excluded from the spec. i would advise to search
or filter based on properties instead. this seems to be something
that may be more portable amongst repositories, even if we would (and i am
not saying we should) implement something like a start-with
method in jackrabbit.

... and to be totally honest, i would really be interested in the use case that
you are operating on. why would someone look for a node name starting
with 'node4' ??

ok, but what if i need to find some node by the part of it's name?
The query  //*[starts-with(name(),'node4')]
complains about starts-with function, which is not implemented. As I can see
from the documentation (JSR 170) there're no starts-with and name functions..

It depends on what you are looking for.
Maybe the unit tests can help : see on
jackrabbit/src/test/org/apache/jackrabbit/test/api/query
I advise you to read the JCR spec. There are many information on
searching support.

Here is a code example :
                        jcrExpression = "/jcr:root/test//element(*,
graffito:paragraph) [jcr:contains(@graffito:text, 'Graffito')]";
			javax.jcr.query.Query jcrQuery =
session.getWorkspace().getQueryManager().createQuery(jcrExpression,
javax.jcr.query.Query.XPATH);

			QueryResult queryResult = jcrQuery.execute();

			NodeIterator nodeIterator = queryResult.getNodes();



			ArrayList result = new ArrayList();

			while (nodeIterator.hasNext())

			{

				Node node = nodeIterator.nextNode();

				log.debug("Node found : " + node.getPath());

				result.add(objectConverter.getObject(session,
query.getFilter().getFilterClass(), node.getPath()));

			}
