Low Search > Keyword-less search using filters? (such as category or custom field)
I can't seem to nail this, but I feel as if Low Search should be able to do this: if I submit a search without a keyword, but have selected a dropdown filter (say a category) ... it should return a list of all the entries in that category as my search results, shouldn't it?
Similarly, if I select a dropdown that was a channel entry, it would show just that channel entry in the results.
Am I missing something here?
I just keep getting 'no results' ... however, the filters seem to work fine when using a keyword (and I do not have 'required' set at all).

Yes, it should. If you're getting no_results, then you might have an issue with the naming of the fields. What does your Low Search Form and Results tag look like? Use http://pastie.org for large chunks of code.

Thanks for looking into this ... here's my code: http://pastie.org/6316950

Try setting the category filter without a group, so:
Mark Elliotson 23 Feb 2013 20:30
Hmm ... that didn't do it.
Here's where I'm at right now > http://pastie.org/6323770

What version of Low Search are you using?
By the looks of your latest code, you're selecting two categories in a single select. I'd try naming both select-elements name="category[]", setting require_all="category" on the Form tag.
Also, as a side note, the limit="24" parameter won't do anything on the Form tag. You should define it on the Results tag.
Mark Elliotson 25 Feb 2013 16:04
Low ... first off ... thanks for the help!
I'm still not getting the desired results here ... I'm on Low Search 2.2.0 running on EE 2.5.5.
Just to reiterate ... the keyword search with and without selecting any of the dropdown parameters works great ... as advertised! The issue I'm facing is that if I select only a dropdown, but do not input a keyword, I get a 'no results' return from my results template.
Here's my current code ... still stuck in the same place: http://pastie.org/6334634
Low 25 Feb 2013 17:11
Can you share your Results tag as well?
Mark Elliotson 25 Feb 2013 18:15
Sure ... thanks!

Low 26 Feb 2013 08:52
This form tag should give you entries that, when a type and colour have been selected, will only return entries that have both categories assigned: http://pastie.org/6339650
This form tag uses multiple select elements, which should give you entries that have (type1, type2 or type3) AND (colour1, colour2 or colour3): http://pastie.org/6339655
If you're still not getting the desired results with either of these two examples, I should take a look myself. Then you can send superadmin login credentials to hi at gotolow dot com.
Mark Elliotson 26 Feb 2013 17:56
Wow ... thanks for work on the code ... very much appreciated!
So I tried out both bits of code and I'm still not getting what I think I should be ... I'm starting to be concerned that perhaps I'm misunderstanding the expected functionality?
I've attached 3 screenshots ... hoping visuals communicate better ... and maybe you can tell me if I'm asking for something that's not possible here.
(This is currently on a MAMP install, so I can't give you superadmin access .... but once I move it to a server, I'll get back to you, if needed).
Let me know what you think after checking out these screen shots ...
Low 26 Feb 2013 19:53
Hmm, it should work. Just tested a similar setup, and it works just fine.
Okay, turn on the template debugger and output profiler, run the query that produces no_results, and copy/paste all the items that contain Low Search in the template debugger, and (if you can) copy the DB queries here, too. Or make a screenshot of those.

By the looks of the debugging data, you're submitting "SEARCH FABRICS ..." as keywords, not an empty string.
Changing the keywords field to this:
Note that the placeholder attribute is a HTML5 attribute that won't show in IE9- but will show in capable browsers.
Mark Elliotson 26 Feb 2013 21:33
Ha ... lol ... well, in the light of day, I guess that makes sense!
Thanks so much for working with me on this!!!
It's all good now!
I'm using this >
<input type="search" name="keywords" value="" placeholder="SEARCH FABRICS ..." onfocus="if(this.placeholder=='SEARCH FABRICS ...') this.placeholder='';" onblur="if(this.placeholder=='') this.placeholder='SEARCH FABRICS ...';" />
Low 26 Feb 2013 21:39
Good!
And you can remove the onfocus="" and onblur="" bits -- the placeholder="" parameter does that automatically (it was added to the HTML5 spec because of that UX pattern).

Hi,
is it possible to achieve the same functionality with filters?
this functionality:
"This form tag uses multiple select elements, which should give you entries that have (type1, type2 or type3) AND (colour1, colour2 or colour3)"
http://pastie.org/6339655
in this code
http://pastie.org/8751560
the goal is the same functionality but without search button, and to look like menu
Low 20 Feb 2014 10:34
You could just create the form with drop downs, and use JS to submit the form onchange of the select elements.
Low 20 Feb 2014 10:39
Or, if you're using filters, make sure you use the category group parameters for each list:
{low_search:url toggle:category:group1="{category_id}"}hrvoje66 21 Feb 2014 07:29
Hi,
that code works, but I have new issue now.
I have a webshop and I use filters for search.
I use {exp:low_search:results} for webshop homepage, and I want to display all items from all categories when page is loaded.
I did that by clicking all categories and copy/paste query from url and putting it as parametar.
Is there more elegant way to do that, display all shop items by default?
Also
My code works well on index shop page, but when on category page, I get warnings:
A PHP Error was encountered
Severity: Warning
Message: array_merge() [function.array-merge]: Argument #1 is not an array
Filename: low_search/mod.low_search.php
Line Number: 1572
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/kolanz/public_html/systemxtr/codeigniter/system/core/Exceptions.php:170)
Filename: core/Common.php
Line Number: 408
I need the search results to work on all shop pages, both index and categories and I need the ability to filter products using low search filters on those pages.
This is my code: http://pastie.org/8754498
EE version: v2.7.3
Low Search version: 3.1.1
Store version: 2.2.0

Hi Low,
I'm trying to do the same thing but can't seem to get it working in EE v2.10.1 and Low Search v4.2.0
I want to allow search by keyword, category or both but can't get it working without a keyword. It works fine if keyword is entered both with and without a category selected, but if you leave the keyword out, I get no results every time (see image)
Form & Results code here: http://pastie.org/10524931
Thanks in advance!
