Re: Autocompletion with Solritas

[Chantal Ackermann]

Hi,

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








$(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

explicit
true
false
json
suggestsrc


terms



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

Cheers,
Chantal

SolrQuery and escaping special characters

[Paolo Castagna]

Hi,
I am using Solr v1.4 and SolrJ on the client side.

I am not sure how SolrJ behaves regarding "escaping" special characters
[1] in a query string.

SolrJ does URL encoding of the query string it sends to Solr.

Do I need to escape special characters [1] when I construct a SolrQuery
object or not?

For example, if I want to search for "http://example.com#foo"; in a
"uri" field, should I use:

 (a)  SolrQuery query = new SolrQuery("uri:http://example.com#foo";);
 (b)  SolrQuery query = new SolrQuery("uri:http\\://example.com#foo");

which become respectively:

 (a') q=uri%3Ahttp%3A%2F%2Fexample.com%23foo
 (b') q=uri%3Ahttp%5C%3A%2F%2Fexample.com%23foo

My understanding is that SolrJ users are supposed to escape special 
characters, therefore (b) is the correct way.


If this is the case, what's the best way to escape a query string which
might contain field names and URIs in their field values?

Thanks,
Paolo

Easiest thing is to use RawQParserPlugin or FieldQParserPlugin.

e.g. SolrQuery.setQuery("{!field f=uri}http://www.apache.org";)



  

custom scoring phrase queries

[Marco Martinez]

Hi,

I want to know if its posiible to get a higher score in a phrase query when
the matching is on the left side of the field. For example:


doc1=name:stores peter john
doc2=name:peter john stores
doc3=name:peter john something

if you do a search with name="peter john" the resultset i want to get is:

doc2
doc3
doc1

because the terms peter john are on the left side of the field and they get
a higher score.

Thanks in advance,

[Erik Hatcher]

Yup, that's basically what I've done too, here's the script part:
  


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