Hi Anja
See my answers below. They are a little short, because I am on my way
out, but I thought "better a short answer than no answer".
Cheers

It depends what your understanding of "sort" is. Typically we sort
pages among the same "hierarchy", e.g. if you have a couple of
child pages below the same parent page, then you can "order" them.
The repository has a hierarchical structure, so we do not really
have something like a "sort".
However, what you see very often, is that you do a search (e.g.
for a date structure) and then sort the result set. This can by
adding a sort order to the search or by iterating through the
resultset, adding e.g. handle and date to a list object and then
sort.
You though also want to consider the beauty of the hierarchical
structure. You mentioned earlier you have the date in the page
title. But you could also look into different scenarios. One I
have used for news archives: I create a page with the handle
representing the year (e.g. /dms/news/2006), there I have child
pages for the months, (e.g. /dms/news/2006/05). And all articles
added have either a day/time type of handle or a news-descriptive
handle and a "issue date" property. So when I add a new article, I
have a small script creating the correct path and storing the
article. This way I can select a date and easily find all articles
for the year, year/month or even year/month/day.
Another idea is not to use the page title for your date, but add a
new property (e.g. in the page porperties or a specific
paragraph). Your search would look for a date value within that
property. This way the title is "free" for a more informative usage.

Hi Giancarlo ,
thanks for your detailed answer.
But I have still one or two questions..
"It depends what your understanding of "sort" is. Typically we sort
pages among the same "hierarchy", e.g. if you have a couple of
child pages below the same parent page, then you can "order" them.
The repository has a hierarchical structure, so we do not really
have something like a "sort". "
How can I order my child pages below a parent page...
The simplest way is of course in the AdminCentral. Click on the left
side Website menu to get the children of a page in the right-side
pane. Then you can just drag and drop the pages.
I assume though that you are trying to display the children pages in
a given order. This means, that you first instantiate a "Content"
object based on the parent page. Then you can use the method
"getChildren(Content.ContentFilter filter, java.util.Comparator
orderCriteria)" to get a Java Collection object containing the
children pages in the order you specify with the Java Comparator.
I recommend that you download the Magnolia Javadoc from
documentation.magnolia.info and check out the "Content" class.
"Another idea is not to use the page title for your date, but add a
new property (e.g. in the page porperties or a specific paragraph).
Your search would look for a date value within that property. This
way the title is "free" for a more informative usage. "
Yes,*now we have a new property added in a specific
paragraph*...But how can we search for a date value withih that
property? Can we use the searchResultSnippet tag for it?
I don't remember if the "searchResultSnippet" tag just does a
fulltext search on a given search term. However, I recommend that you
use the "QueryManager" to build the search. You can use a SQL like
search statement, e.g. "SELECT * FROM mgnl:content LOCATION "/
myParent/myNews/* WHERE {propertyname} LIKE "2007%" ORDER BY
propertyname". In the FROM clause you have the nodetype (e.g. * or
mgnl:content or whatever nodetype you want), the LOCATION clause
specifies which handles to search and the WHERE clause can be used to
search properties.
I recommend you download the JSR 170 specs from jcp.org/en/jsr/detail?
id=170. There is a detailed description about the search term. And
btw: you can also use XPath to search.
How can I add a search order to a search? *Could you specify what
you mean with "adding handle and a date to list object and then
sort" ? *
On a second thought it's not such a good idea :-) I was thinking of
iterating through the child pages, creating a Java List object with
some values and using the Collection.sort() method to sort them to
whatever order you want to represent. This I use when I have specific
properties/values I want to check (e.g. "showInNavigation", an
expired date, etc. If it's a search, then follow above.
I don't know how I can sort my results after searching by a specify
property
Use the JCRQL language as described above (or XPath).
Sorry,but we are very unversed with searching for pages and sort of
pages...
No problem!
Many thanks for a reply......
