Can Low Alphabet search by relationship field?
I have a channel where entries should be filtered by alphabet if segment_2 = alpha, by a category if segment_2 = division and by a native relationship field if it = location.
alpha_filter and category parameters on exp:low_alphabet:entries both work fine but is it possible to use the search parameter on related entries or some other method?

The native Relationship field doesn't store anything in the exp_channel_data table, which means you can't use the search:field="" parameter on it. This is true for the native channel:entries tag, and therefore for the low_alphabet:entries tag, too.
Playa does store searchable data in said table, so if you were using that, you could.
Instead, you could be looking at Low Search for filtering by Relationship, which would take an entry ID (or IDs), just like the category param.
Note that Low Search can also filter by first letter, using the Field Search filter with the starts_with parameter.

So I should be able to do
child:location="{if segment_2=='location'}{segment_3}{/if}"
in the exp:low_search:results tag? Because when I try that (or with parent:expert_location) I get no result for a URL like /template_group/location/XX

The Relationships filter only takes entry IDs as a parameter. However, I'll soon release an update which will make it accept url_titles, too.

Sorry, didn't make it clear, in my example, XX, segment_3 is an entry_id.

Then using child:location="123" should give you all the entries that have entry ID 123 as a child through the relationship field named 'location'. So, that's entries that have the field 'location' in its publish form where entry ID 123 is selected.

Hmm, not getting any results. Example code: http://pastie.org/9711174

I'll need to take a look myself. Please send SuperAdmin login credentials to hi at gotolow dot com if you can.

Before I do that, can I just confirm that I can use the results tag without needing a form, that I can just link to URLs that should produce results?

Yes, you can use the Results tag as a replacement for the channel:entries tag.
