[Koha] Embedding search form with branch limit

[Karen Myers]

Hi all

Hoping someone may be able to help me with this - I've searched online but cant find a solution. I am embedding a search box in the website of of one of our member libraries using the code below, however I want to limit the search to that 1 member library's materials.
What else to i need to add to ensure it just returns results from the 1 member library rather than all our libraries?


<form name="searchform" method="get" action="http://159.65.65.143/cgi-bin/koha/opac-search.pl" id="searchform">
<input id="transl1" name="q" type="text"><p>
<select name="idx" id="masthead_search">
<option value="kw">Keyword</option>
<option value="ti">Title</option>
<option value="au">Author</option>
<option value="su">Subject</option>
<option value="nb">ISBN</option>
<option value="se">Series</option>
<option value="callnum">Call Number</option>
</select>
<input value="Search" id="searchsubmit" type="submit">
</p></form>

Thanks in advance.

Karen
