Re: Autocompletion with Solritas

Hi Erik,

Just used jQuery's autocomplete plugin and the terms component for  
now, on the name field.  Quite simple to plug in, actually.  Check  
the commit diff.  The main magic is doing this:

  <http://localhost:8983/solr/terms?terms.fl=name&terms.prefix=i&terms.sort=count&wt=velocity&v.template=suggest

Stupidly, though, jQuery's autocomplete seems to be hardcoded to  
send a q parameter, but I coded it to also send the same value as  
terms.prefix - but this could be an issue if hitting a different  
request handler where q is used for the actual query for filtering  
terms on.

Let's say, just for grins, that a different field (besides "name") is  
being used for autocompletion.

What would be all the places I'd need to hit to change the field,  
besides the terms.fl value in layout.vm? For example, what about  
browse.vm:

    $("input[type=text]").autoSuggest("/solr/suggest",  
{selectedItemProp: "name", searchObjProps: "name"}});

I'm asking because I'm trying to use this latest support with an index  
that uses "product_name" for the auto-complete field, and I'm not  
getting any auto-completes happening.

I see from the Solr logs that requests being made to /solr/terms  
during auto-complete that look like:

INFO: [] webapp=/solr path=/terms  
params 
= 
{limit 
= 
10 
&timestamp 
= 
1276903135595 
&terms 
.fl 
= 
product_name 
&q 
=rug&wt=velocity&terms.sort=count&v.template=suggest&terms.prefix=rug}  
status=0 QTime=0

Which I'd expect to work, but don't seem to be generating any results.

What's odd is that if I try curling the same thing:

curl -v "http://localhost:8983/solr/terms?limit=10&timestamp=1276903135595&terms.fl=product_name&q=rug&wt=velocity&terms.sort=count&v.template=suggest&terms.prefix=rug 
"

I get an empty HTML response:

< Content-Type: text/html; charset=utf-8
< Content-Length: 0
< Server: Jetty(6.1.22)

If I just use what I'd consider to be the minimum set of parameters:

curl -v "http://localhost:8983/solr/terms?limit=10&terms.fl=product_name&q=rug&terms.sort=count&terms.prefix=rug 
"

Then I get the expected XML response:

< Content-Type: text/xml; charset=utf-8
< Content-Length: 225
< Server: Jetty(6.1.22)
<
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int  
name="QTime">0</int></lst><lst name="terms"><lst  
name="product_name"><int name="rug">7</int></lst></lst>
</response>

Any ideas what I'm doing wrong?

Thanks,

I don't believe Solritas supports autocompletion out of the box.

So I'm wondering if anybody has experience using the LucidWorks  
distro & Solritas, plus the AJAX Solr auto-complete widget.

I realize that AJAX Solr's autocomplete support is mostly just  
leveraging the jQuery Autocomplete plugin, and hooking it up to  
Solr facets, but I was curious if there were any tricks or traps in  
getting it all to work.

Thanks,
