Re: Autocompletion with Solritas

[Erik Hatcher]

Yup, that's basically what I've done too, here's the script part:
  <http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/conf/velocity/layout.vm?view=markup

I didn't touch the example solrconfig, though putting the params in  
the request handler is the better way, as you have.

Hi,

here is my solution. It has been some time since I last looked at it,
but it works fine. :-)

<script type="text/javascript"
src="/solr/epg/admin/file?file=/velocity/ 
jquery-1.4.min.js&contentType=text/javascript"></script>
<script type="text/javascript"
src="/solr/epg/admin/file?file=/velocity/jquery- 
ui.js&contentType=text/javascript"></script>
<script type="text/javascript"
src="/solr/epg/admin/file?file=/velocity/ 
jquery.autocomplete.js&contentType=text/javascript"></script>
<link rel="stylesheet" type="text/css"
href="/solr/epg/admin/file?file=/velocity/ 
jquery.autocomplete.css&contentType=text/css"/>

<script type="text/javascript"
src="/solr/epg/admin/file?file=/velocity/ 
jquery.json-2.2.min.js&contentType=text/javascript"></script>

$(function() {
        $("#qterm").autocomplete('/solr/epg/suggest', {
                extraParams: {
                        'terms.prefix': function() { return $("#qterm").val(); }
                },
                hightlight: false,
                max: 30,
                formatItem: function(row, i, n) {
                        return row;
                },
                parse: function(data) {
                        var json =  jQuery.secureEvalJSON(data);
                        var terms = json.terms;
                        var suggMap = terms[1];
                        var suggest = [];
                        var j = 0;
                        for (i=0; i<suggMap.length; i=i+2) {
                                suggest[j] = {
                                        data: suggMap[i],
                                        value: suggMap[i],
                                        result: suggMap[i]
                                }
                                j = j+1;
                        }
                                
                        return suggest;
                }
        });
});

#qterm is the form's input text field.
in solrconfig.xml:

        <requestHandler name="/suggest" class="solr.SearchHandler" >
                <lst name="defaults">
                        <str name="echoParams">explicit</str>
                        <bool name="terms">true</bool>
                        <bool name="terms.lower.incl">false</bool>
                        <str name="wt">json</str>
                        <str name="terms.fl">suggestsrc</str>
                </lst>
                <arr name="components">
                        <str>terms</str>
                </arr>
        </requestHandler>

suggestsrc is of type solr.TextField, accumulated from different  
source
fields.
