I have a project with a song library... a song dataobject and two related data objects, theme and subtheme. I've created a search form where the user can search using a combination of text boxes and drop downs and limited it to showing 10 songs per page. The search works - but when you click the link to move to the next page in the set of results it seems to effectively start a "blank" search - i.e. instead of moving to page 2 of results matching the users query it moves to page 2 of a result set that contains every song in the library.
Code for SongSearch_Results.ss below:
<div id="rightcol">
<% include SongLibrarySideSearch %>
$Sidebar
</div><!-- End Right Col Div -->
<div id="leftcol">
<h1>SEARCH RESULTS</h1>
<% if Results %>
<% if Results.MoreThanOnePage %>
<p><b>We found over 10 songs matching your search, this is page $Results.CurrentPage of $Results.TotalPages :</b></p>
<% else %>
<p><b>We found $Results.Count song(s) matching your search :</b></p>
<% end_if %>
<% control Results %>
<h3>$Title</h3><p><b>Written by: </b>$Author<p><b>Lyrics: </b>$Lyrics.LimitWordCount(30)...</p>
<p><a href="/song-library/showsong/$ID" class="morebtn" title="$Title"><span class="displace">$Title</span></a>
<div class="line"></div>
<div class="clear"></div>
<% end_control %>
<p><b>You can <a href="/song-library">click here</a> to start a new search.</b></p>
<% else %>
<p>Sorry, we couldn't find any songs matching your search. Please <a href="/song-library">click here</a> to try again.</p>
<% end_if %>
<% if Results.MoreThanOnePage %>
<div id="PageNumbers">
<p>
<% if Results.NotFirstPage %>
<a class="prev" href="$Results.PrevLink" title="View the previous page">Prev</a>
<% end_if %>
<span>
<% control Results.PaginationSummary(4) %>
<% if CurrentBool %>
$PageNum
<% else %>
<% if Link %>
<a href="$Link" title="View page number $PageNum">$PageNum</a>
<% else %>
…
<% end_if %>
<% end_if %>
<% end_control %>
</span>
<% if Results.NotLastPage %>
<a class="next" href="$Results.NextLink" title="View the next page">Next</a>
<% end_if %>
</p>
</div>
<% end_if %>
</div>
