Search URL
When performing a search or clicking on the details links, Evergreen constructs a GET request url with the parameters of the search. The url for searches and details in Evergreen are persistent links in that they can be saved, shared and used later.
Here is a basic search URL structure:
[hostname]/opac/[locale]/skin/default/xml/rresult.xml?rt=keyword&tp=keyword&t=[search term]&l=[location id]&d=0
l Parameter
This is the id of the search location. It is an integer and maches the id of the location the user selected in the location drop down menu.
This is accompanied by a d parameter which indicated the depth of the location selected. For example, 0 would be the highest level and 1 would represent the next depth level.
rt Parameter
The rt parameter in the URL represents the search type values and represent one of the following search or request types:
keyword
title
author
subject
series
These match the options in the search type drop-down box.
Sorting
The s parameter sorts the results on one of these criteria.
pubdate (publication date) - chronological order
title - Alphabetical order
author - Alphabetical order on family name first
The sd indicates the direction to sort
asc - ascending
desc - descending
In the absence of s or sd parameter, the search results default to sorting by relevance.
Advanced search (multiple fields)
Uses rt=multi; then prepend search field to the search terms (delimited by a colon) in the t parameter:
...tp=&t=keyword%3Afools title%3Arush&av=&rt=multi
ISBN and ISSN search include the following in the URL:
...rt=isbn&adv=...
...rt=issn&adv=...
Call number search will include:
...cnbrowse.xml?cn=pr5655...
