Search Results Pagination
When a
%SEARCH{...}%
returns many results, you may want to paginate the results.
Overview
You can achieve search results pagination by tweaking a
%SEARCH{...}%
as follows.
(New lines are inserted for readability in
$SET(searchparams, ...)
. Please don't copy-paste it for real use.)
As you can see, this is using the
SpreadSheetPlugin.
...
%INCLUDE{"%SYSTEMWEB%.SearchResultsPagination" section="preamble"}%<nop>
%SEARCH{
"%URLPARAM{"search" encode="quote"}%"
...
start="%CALCULATE{$GET(start)}%"
limit="%CALCULATE{$GET(limit)}%"
footer="$percntCALCULATE{$SET(ntopics, $tntopics)$SET(nwebs, $nwebs)}$percnt"
}%
%CALCULATE{$SET(searchparams, search=%URLPARAM{"search" encode="quote"}%;
type=%URLPARAM{"type" encode="quote" default="%SEARCHDEFAULTTYPE%"}%;
scope=%URLPARAM{"scope" encode="quote"}%;
web=%URLPARAM{"web" encode="quote"}%;
nosearch=%URLPARAM{"nosearch" encode="quote"}%;)}%<nop>
%INCLUDE{"%SYSTEMWEB%.SearchResultsPagination" section="postamble"}%<nop>
...
This tweaking adds pagination link rows before and after the search results as follows:
«Prev 1 2 3 4 5 Next»
The
section="preamble"
and
section="postamble"
also support a
style=""
parameter to set the style of the pagination link row
<div>
tag. For example, to disable the pagination link row on top, write:
%INCLUDE{"%SYSTEMWEB%.SearchResultsPagination" section="preamble" style="display:none;"}%<nop>
Maximum 16 page links are shown — the "Next" link can be used to paginate beyond 16 pages if there are more than that. The pagination link rows are not shown if the number of results is below a one page threshold.
WebChanges,
WebSearch, and
WebSearchAdvanced are using this technique.
Results per page
By default, each page shows 50 results, which is defined by the SEARCHRESULTSPERPAGE preferences setting.
To change it to 10, change the initial part as follows.
(The second line is inserted.)
%INCLUDE{"%SYSTEMWEB%.SearchResultsPagination" section="preamble"}%<nop>
%CALCULATE{$SET(limit, %URLPARAM{"limit" default="10"}%)}%<nop>
%SEARCH{
If you specify
limit=20
URL parameter manually, that's observed.
If you specify
limit=all
URL parameter, all results are shown without pagination.
URL parameters
All hyper links in the pagination apparatus point to the same page with some URL parameters.
The parameters are plus pagination parameters (namely
start
and
limit
).
You need to
$SET(searchparams, ...)
having this in mind.
Multiple webs
%SEARCH{...}%
may take the
web
parameter to have multiple webs specified.
In that case, it's strange to do pagination hence suppressed.
SpreadSheetPlugin variables
This feature uses the following
SpreadSheetPlugin variables.
Please beware of variable clashes if you use
SpreadSheetPlugin for your own use on a page doing search result pagination
